The PTH05050W is one of the smallest non-isolated power modules from Texas Instruments that featuresAuto-Track™ sequencing. Auto-Track simplifies supply voltage sequencing in power systems by enablingmodules to track each other, or any other external voltage, during power up and power down.
Although small in size (0.87 in × 0.5 in), these modules are rated for up to 6 A of output current, and are an idealchoice in applications where space, performance, and a power-up sequencing capability are important attributes.
The product provides high-performance step-down conversion from a 5-V input bus voltage. The output voltageof the PTH05050W can be set to any voltage over the range, 0.8 V to 3.6 V, using single resistor.
Other operating features include an on/off inhibit, output voltage adjust (trim), and output over-current protection.For high efficiency these parts employ a synchronous rectifier output stage, but a pre-bias hold-off capabilityensures that the output will not sink current during startup.
Target applications include telecom, industrial, and general purpose circuits, including low-power dual-voltagesystems that use a DSP, microprocessor, ASIC, or FPGA.
Package options include both throughhole and surface mount configurations.

SET
has atolerance of 1% with 100 ppm/ ° C or better temperature stability.(3) The pk-pk output ripple voltage is measured with an external 10 µ F ceramic capacitor. See the standard application schematic.(4) This control pin has an internal pull-up to the input voltage. If it is left open-circuit the module will operate when input power is applied. Asmall, low leakage ( < 100 nA) MOSFET or open-drain/collector voltage supervisor IC is recommended for control. Do not place anexternal pull-up on this pin. For further information, consult the related application note.(5) A 100 µ F input capacitor are required for proper operation. The capacitor must be rated for a minimum of 300 mA rms of ripple current.(6) An external output capacitor is not required for basic operation. Adding 100 µ F of distributed capacitance at the load will improve thetransient response.(7) This is the calculated maximum. The minimum ESR limitation will often result in a lower value. When controlling the Track pin using avoltage supervisor, C
O
(max) is reduced to 2200 µF. Consult the application notes for further guidance.(8) This is the typical ESR for all the electrolytic (non-ceramic) output capacitance. Use 7 m Ωas he minimum when using max-ESR valuesto calculate.

TERMINAL
DESCRIPTIONNAME NO.
Vin 3 The positive input voltage power node to the module, which is referenced to common GND.
Vout 6 The regulated positive power output with respect to the GND node.
This is the common ground connection for the Vin and Vout power connections. It is also the 0 VDC reference forGND 1
the control inputs.
A 0.05 W 1% resistor must be directly connected between this pin and (GND) to set the output voltage to a valuehigher than 0.8 V. The temperature stability of the resistor should be 100 ppm/ ° C (or better). The set point range forthe output voltage is from 0.8 V to 3.6 V. The resistor value required for a given output voltage may be calculatedfrom the following formula. If left open circuit, the output voltage will default to its lowest value. For furtherinformation on output voltage adjustment consult the related application note.Vo Adjust 5
The specification table gives the preferred resistor values for a number of standard output voltages.
The Inhibit pin is an open-collector/drain negative logic input that is referenced to GND. Applying a low-level groundsignal to this input disables the module ’ s output and turns off the output voltage. When the Inhibit control is active,Inhibit
(1)

the input current drawn by the regulator is significantly reduced. If the Inhibit pin is left open-circuit, the module willproduce an output whenever a valid input source is applied.
This is an analog control input that enables the output voltage to follow an external voltage. This pin becomesactive typically 20 ms after the input voltage has been applied, and allows direct control of the output voltage from 0V up to the nominal set-point voltage. Within this range the output will follow the voltage at the Track pin on aTrack 2
volt-for-volt basis. When the control voltage is raised above this range, the module regulates at its set-point voltage.The feature allows the output voltage to rise simultaneously with other modules powered from the same input bus.If unused, this input should be connected to V
in
.
Note: Due to the under-voltage lockout feature, the output of the module cannot follow its own input voltage duringpower up. For more information, consult the related application note.

The recommended input capacitor(s) is determined by the 100 µF minimum capacitance and 300 mArmsminimum ripple current rating.
Ripple current, less than 100 m Ωequivalent series resistance (ESR), and temperature are the majorconsiderations when selecting input capacitors. Unlike polymer tantalum, regular tantalum capacitors have arecommended minimum voltage rating of 2 × (maximum DC voltage + AC ripple). This is standard practice toensure reliability.
For improved ripple reduction on the input bus, ceramic capacitors may used to compliment electrolytic types toachieve the minimum required capacitance.
For applications with load transients (sudden changes in load current), regulator response will benefit from anexternal output capacitance. The recommended output capacitance of 100 µF will allow the module to meet itstransient response specification (see product data sheet). For most applications, a high quality computer-gradealuminum electrolytic capacitor is adequate. These capacitors provide decoupling over the frequency range,2 kHz to 150 kHz, and are suitable for ambient temperatures above 0 ° C. For operation below 0 ° C tantalum,ceramic or OS-CON type capacitors are recommended. When using one or more non-ceramic capacitors, thecalculated equivalent ESR should be no lower than 4 m Ω(7 m Ωusing the manufacturer's maximum ESR for asingle capacitor). A list of preferred low-ESR type capacitors are identified in Table 3 .
Above 150 kHz the performance of aluminum electrolytic capacitors becomes less effective. To further improvethe reflected input ripple current or the output transient response, multilayer ceramic capacitors can also beadded. Ceramic capacitors have very low ESR and their resonant frequency is higher than the bandwidth of theregulator. When used on the output their combined ESR is not critical as long as the total value of ceramiccapacitance does not exceed 300 µF. Also, to prevent the formation of local resonances, do not place more thanfive identical ceramic capacitors in parallel with values of 10 µF or greater.
Tantalum type capacitors can be used at both the input and output, and are recommended for applications wherethe ambient operating temperature can be less than 0 ° C. The AVX TPS, Sprague 593D/594/595 and KemetT495/T510 capacitor series are suggested over many other tantalum types due to their higher rated surge, powerdissipation, and ripple current capability. As a caution many general purpose tantalum capacitors haveconsiderably higher ESR, reduced power dissipation and lower ripple current capability. These capacitors arealso less reliable as they have reduced power dissipation and surge current ratings. Tantalum capacitors that donot have a stated ESR or surge current rating are not recommended for power applications.
When specifying OS-CON and polymer tantalum capacitors for the output, the minimum ESR limit will beencountered well before the maximum capacitance value is reached.
Table 3 identifies the characteristics of capacitors from a number of vendors with acceptable ESR and ripplecurrent (RMS) ratings. The recommended number of capacitors required at both the input and output buses isidentified for each capacitor type.
This is not an extensive capacitor list. Capacitors from other vendors are available with comparablespecifications. Those listed are for guidance. The RMS ripple current rating and ESR (at 100 kHz) are criticalparameters necessary to insure both optimum regulator performance and long capacitor life.

The transient response of the DC/DC converter has been characterized using a load transient with a di/dt of1 A/ µs. The typical voltage deviation for this load transient is given in the data sheet specification table using theoptional value of output capacitance. As the di/dt of a transient is increased, the response of a converter'sregulation circuit ultimately depends on its output capacitor decoupling network. This is an inherent limitation withany DC/DC converter once the speed of the transient exceeds its bandwidth capability. If the target applicationspecifies a higher di/dt or lower voltage deviation, the requirement can only be met with additional outputcapacitor decoupling. In these cases special attention must be paid to the type, value and ESR of the capacitorsselected.
If the transient performance requirements exceed that specified in the data sheet, or the total amount of loadcapacitance is above 3000 µF, the selection of output capacitors becomes more important.
The PTH/PTV family of non-isolated, wide-output adjust power modules from Texas Instruments are optimizedfor applications that require a flexible, high performance module that is small in size. Each of these products arePOLA™ compatible. POLA-compatible products are produced by a number of manufacturers, and offercustomers advanced, non-isolated modules with the same footprint and form factor. POLA parts are also assuredto be interoperable, thereby providing customers with true second-source availability.
From the basic, Just Plug it In functionality of the 6-A modules, to the 30-A rated feature-rich PTHxx030, theseproducts were designed to be very flexible, yet simple to use. The features vary with each product. Table 4provides a quick reference to the features by product series and input bus voltage.

The Auto-Track feature allows the power-up of multiple modules to be directly controlled from the Track pin.However in a stand-alone configuration, or when the Auto-Track feature is not being used, the Track pin shouldbe directly connected to the input voltage, V
in
(see Figure 6 ).
Figure 6.
When the Track pin is connected to the input voltage the Auto-Track function is permanently disengaged. Thisallows the module to power up entirely under the control of its internal soft-start circuitry. When power up isunder soft-start control, the output voltage rises to the set-point at a quicker and more linear rate.
Figure 7.
From the moment a valid input voltage is applied, the soft-start control introduces a short time delay (typically5ms-10ms) before allowing the output voltage to rise. The output then progressively rises to the module ’ ssetpoint voltage. Figure 7 shows the soft-start power-up characteristic of the 22-A output product (PTH05020W),operating from a 5-V input bus and configured for a 3.3-V output. The waveforms were measured with a 5-Aresistive load, with Auto-Track disabled. The initial rise in input current when the input voltage first starts to rise isthe charge current drawn by the input capacitors. Power-up is complete within 15 ms.
For protection against load faults, all modules incorporate output over-current protection. Applying a load thatexceeds the regulator's over-current threshold will cause the regulated output to shut down. Following shutdowna module will periodically attempt to recover by initiating a soft-start power-up. This is described as a hiccupmode of operation, whereby the module continues in a cycle of successive shutdown and power up until the loadfault is removed. During this period, the average current flowing into the fault is significantly reduced. Once thefault is removed, the module automatically recovers and returns to normal operation.

For applications requiring output voltage on/off control, each series of the PTH family incorporates an outputInhibit control pin. The inhibit feature can be used wherever there is a requirement for the output voltage from theregulator to be turned off. The power modules function normally when the Inhibit pin is left open-circuit, providinga regulated output whenever a valid source voltage is connected to V
I
with respect to GND.
Figure 8 shows the typical application of the inhibit function. Note the discrete transistor (Q
1
). The Inhibit controlhas its own internal pull-up to V
in
potential. The input is not compatible with TTL logic devices. An open-collector(or open-drain) discrete transistor is recommended for control.
Figure 8. Figure 9.
Turning Q
1
on applies a low voltage to the Inhibit control and disables the output of the module. If Q
1
is thenturned off, the module will execute a soft-start power-up. A regulated output voltage is produced within 20 msec.Figure 9 shows the typical rise in both the output voltage and input current, following the turn-off of Q
1
. The turnoff of Q1 corresponds to the rise in the waveform, Q

. The waveforms were measured with a 5-A load.
The Auto-Track function is unique to the PTH/PTV family, and is available with all POLA products. Auto-Trackwas designed to simplify the amount of circuitry required to make the output voltage from each module power upand power down in sequence. The sequencing of two or more supply voltages during power up is a commonrequirement for complex mixed-signal applications that use dual-voltage VLSI ICs such as the TMS320™ DSPfamily, microprocessors, and ASICs.
How Auto-Track™ Works
Auto-Track works by forcing the module output voltage to follow a voltage presented at the Track control pin
(1)
.This control range is limited to between 0 V and the module set-point voltage. Once the track-pin voltage israised above the set-point voltage, the module output remains at its set-point
(2)
. As an example, if the Track pinof a 2.5-V regulator is at 1 V, the regulated output is 1 V. If the voltage at the Track pin rises to 3 V, the regulatedoutput does not go higher than 2.5 V.
Under Auto-Track control, the regulated output from the module follows the voltage at its Track pin on avolt-for-volt basis. By connecting the Track pin of a number of these modules together, the output voltages followa common signal during power up and power down. The control signal can be an externally generated masterramp waveform, or the output voltage from another power supply circuit
(3)
. For convenience, the Track inputincorporates an internal RC-charge circuit. This operates off the module input voltage to produce a suitable risingwaveform at power up.

Typical Auto-Track™ Application
The basic implementation of Auto-Track allows for simultaneous voltage sequencing of a number of Auto-Trackcompliant modules. Connecting the Track inputs of two or more modules forces their track input to follow thesame collective RC-ramp waveform, and allows their power-up sequence to be coordinated from a common trackcontrol signal. This can be an open-collector (or open-drain) device, such as a power-up reset voltage supervisorIC. See U3 in Figure 10 .
To coordinate a power-up sequence, the Track control must first be pulled to ground potential. This should bedone at or before input power is applied to the modules. The ground signal should be maintained for at least20 ms after input power has been applied. This brief period gives the modules time to complete their internalsoft-start initialization
(4)
, enabling them to produce an output voltage. A low-cost supply voltage supervisor IC,that includes a built-in time delay, is an ideal component for automatically controlling the track inputs at powerup.
Figure 10 shows how the TPS3808G50 supply voltage supervisor IC (U3) can be used to coordinate thesequenced power-up of two 5-V input Auto-Track modules. The output of the TPS3808G50 supervisor becomesactive above an input voltage of 0.8 V, enabling it to assert a ground signal to the common track control wellbefore the input voltage has reached the module's undervoltage lockout threshold. The ground signal ismaintained until approximately 27 ms after the input voltage has risen above U3's voltage threshold, which is4.65 V. The 27-ms time period is controlled by the capacitor C3. The value of 4700 pF provides sufficient timedelay for the modules to complete their internal soft-start initialization. The output voltage of each moduleremains at zero until the track control voltage is allowed to rise. When U3 removes the ground signal, the trackcontrol voltage automatically rises. This causes the output voltage of each module to rise simultaneously with theother modules, until each reaches its respective set-point voltage.
Figure 11 shows the output voltage waveforms from the circuit of Figure 10 after input voltage is applied to thecircuit. The waveforms, V
O
1 and V
O
2 represent the output voltages from the two power modules, U1 (3.3 V) andU2 (1.8 V), respectively. V
TRK
, V
O
1, and V
O
2 are shown rising together to produce the desired simultaneouspower-up characteristic.
The same circuit also provides a power-down sequence. When the input voltage falls below U3's voltagethreshold, the ground signal is re-applied to the common track control. This pulls the track inputs to zero volts,forcing the output of each module to follow, as shown in Figure 12 . In order for a simultaneous power-down tooccur, the track inputs must be pulled low before the input voltage has fallen below the modules' undervoltagelockout. This is an important constraint. Once the modules recognize that a valid input voltage is no longerpresent, their outputs can no longer follow the voltage applied at their track input. During a power-downsequence, the fall in the output voltage from the modules is limited by the maximum output capacitance and theAuto-Track slew rate. If the Track pin is pulled low at a slew rate greater than 1 V/ms, the discharge of the outputcapacitors will induce large currents which could exceed the peak current rating of the module. This will result ina reduction in the maximum allowable output capacitance as listed in the Electrical Characteristics table. Whencontrolling the Track pin of the PTH05050W using a voltage supervisor IC, the slew rate is increased, thereforeC
O
max is reduced to 2200 µF.
Notes on Use of Auto-Track™
1. The Auto-Track function tracks almost any voltage ramp during power up, and is compatible with rampspeeds of up to 1 V/ms.
2. The Track pin voltage must be allowed to rise above the module set-point voltage before the moduleregulates at its adjusted set-point voltage.
3. The absolute maximum voltage that may be applied to the Track pin is the input voltage V
I
.
4. The module cannot follow a voltage at its track control input until it has completed its soft-start initialization.This takes about 20 ms from the time that a valid voltage has been applied to its input. During this period, itis recommended that the Track pin be held at ground potential.
5. The Auto-Track function is disabled by connecting the Track pin to the input voltage (V
I
). When Auto-Track isdisabled, the output voltage rises at a quicker and more linear rate after input power has been applied.

Only selected products in the PTH family incorporate this capability. Consult Table 4 to identify which productsare compliant.
A pre-bias startup condition occurs as a result of an external voltage being present at the output of a powermodule prior to its output becoming active. This often occurs in complex digital systems when current fromanother power source is backfed through a dual-supply logic component, such as an FPGA or ASIC. Anotherpath might be via clamp diodes as part of a dual-supply power-up sequencing arrangement. A prebias can causeproblems with power modules that incorporate synchronous rectifiers. This is because under most operatingconditions, these types of modules can sink as well as source output current.
The PTH family of power modules incorporate synchronous rectifiers, but will not sink current during startup
(1)
, orwhenever the Inhibit pin is held low. However, to ensure satisfactory operation of this function, certain conditionsmust be maintained
(2)
.Figure 13 shows an application demonstrating the pre-bias startup capability. The startupwaveforms are shown in Figure 14 . Note that the output current from the PTH03010W (I
O
) shows negligiblecurrent until its output voltage rises above that backfed through the ASIC's intrinsic diodes.Note: The pre-bias start-up feature is not compatible with Auto-Track. When the module is under Auto-Trackcontrol, it will sink current if the output voltage is below that of a back-feeding source. To ensure a pre-biashold-off one of two approaches must be followed when input power is applied to the module. The Auto-Trackfunction must either be disabled
(3)
, or the module's output held off (for at least 50 ms) using the Inhibit pin.Either approach ensures that the Track pin voltage is above the set-point voltage at start up.
Notes:
1. Startup includes the short delay (approximately 10 ms) prior to the output voltage rising, followed by the riseof the output voltage under the module's internal soft-start control. Startup is complete when the outputvoltage has risen to either the set-point voltage or the voltage at the Track pin, whichever is lowest.
2. To ensure that the regulator does not sink current when power is first applied (even with a ground signalapplied to the Inhibit control pin), the input voltage must always be greater than the output voltage throughoutthe power-up and power-down sequence.
3. The Auto-Track function can be disabled at power up by immediately applying a voltage to the module'sTrack pin that is greater than its set-point voltage. This can be easily accomplished by connecting the Trackpin to V
I
.
