Description
The TS30011 (1A), TS30012 (2A) and TS30013 (3A) are DC/DC
synchronous switching regulator with fully integrated power
switches, internal compensation, and full fault protection. The
switching frequency of 1MHz enables the use of small filter
components resulting in minimal board space and reduced
BOM costs.
The TS30011/12/13 utilizes current mode feedback in normal
regulation PWM mode. When the regulator is placed in
standby (EN is low), the device draws less than 10uA quiescent
current.
The TS30011/12/13 integrates a wide range of protection
circuitry including input supply under-voltage lockout, output
voltage soft start, current limit, and thermal shutdown.
The TS30011/12/13 includes supervisory reporting through
the PG (Power Good) open drain output to interface other
components in the system.

Functional Description
The TS30011/12/13 current-mode synchronous step-down
regulator is ideal for use in the commercial, industrial, and
automotive market segments. It includes flexibility to be
used for a wide range of output voltages and is optimized for
high efficiency power conversion with low RDSON integrated
synchronous switches. A 1MHz internal switching frequency
facilitates low cost LC filter combinations. Additionally, the
fixed output versions enable reduce the external component
count and provide a complete regulation solution with only 4
external components: an input bypass capacitor, an inductor,
an output capacitor, and the bootstrap capacitor. The regulator
automatically transitions between PFM and PWM mode to
maximize efficiency for the load demand.
The TS30011/12/13 provides these system benefits:
• Reduced board real estate
• Lower system cost
Lower cost inductor
Low external parts count
• Ease of design

Detailed Pin Description
Unregulated input, VCC
This terminal is the unregulated input voltage source for the
IC. It is recommended that a 10uF bypass capacitor be placed
close to the device for best performance. Since this is the main
supply for the IC, good layout practices need to be followed for
this connection.
Bootstrap control, BST
This terminal provides the bootstrap voltage required for the
upper internal NMOS switch of the buck regulator. An external
ceramic capacitor placed between the BST input terminal and
the VSW pin provides the necessary voltage for the upper
switch. In normal operation the capacitor is recharged on
every switching cycle when the low-side NMOS is on.
In the case of where the switch mode approaches 100% duty
cycle for the high side FET, the device automatically reduces
the duty cycle switch to a minimum off time on every 8th cycle
to allow this capacitor to re-charge
Sense feedback, FB
This is the input terminal for the output voltage feedback.
For the fixed output versions, this should be hooked directly to
VOUT. The PCB connection should be kept as short as possible,
and should be made as close as possible to the output
capacitor. The trace should not be shared with any other
connection. (Figure 24)
For adjustable output versions, the FB input should be
connected to the external resistor divider. To choose the
resistors, use the following equation:
VOUT = 0.9 (1 + RTOP/RBOT )
The FB input is high impedance and input current should be
less than 100nA. As a result, good layout practices are required
for the feedback resistors and feedback traces. When using the
adjustable version, the feedback trace should be kept as short
as possible with minimum width to reduce stray capacitance
and to reduce the injection of noise.
For adjustable output versions, the ratio of VCC/VOUT cannot
exceed 16.
Switching output, VSW
This is the switching node of the regulator. It should be
connected directly to the 4.7uH inductor with a wide, short
trace and also to one end of the Bootstrap capacitor. This node
switches between VCC and PGND at the switching frequency.
Ground, GND
This ground is used for the majority of the device including the
analog reference, control loop, and other circuits.
Power Ground, PGND
This is a separate power ground connection used for the low-
side synchronous switch, to isolate switching noise from the
rest of the device. (Figure 24)
Enable, EN
This is the input terminal to activate the regulator. The input
threshold is TTL/CMOS compatible. It also has an internal pull-
up to ensure a stable state if the pin is disconnected.

Power Good Output, PG
This is an open drain output. During start-up the FB input is
monitored and the PG line remains low, until the FB voltage
reaches the VOUT_UV threshold. A 10KΩ resistor to VOUT is
required for pull-up. Once the internal comparator detects
that the FB voltage is above the desired threshold, an internal
delay timer is activated and the PG line is de-asserted to high
once this delay timer expires. In the event of a fault, when the
FB voltage decreases below VOUT_UV, the PG line asserts low and
remains low until the FB input exceeds VOUT_UV and the delay
timer times out. See Figure 3 for the control of the PG signal.
Internal Protection Details
Internal Current Limit
The high-side NMOS current is sensed on a cycle by cycle basis
and if current limit is reached, the IC truncates the high-side
on-time. The device also senses the FB pin to identify hard
output shorts or extended over-current conditions. It then
directs the VSW output to skip 4 cycles and frequency will
foldback to 250KHz, if current limit occurs when FB is low. This
allows current built up in the inductor during the minimum on
time to decay sufficiently. Current limit is always active when
the regulator is enabled. Soft start ensures current limit does
not prevent regulator startup.
Once the over current condition is removed, the device returns
to normal operation automatically. (Alternately the factory can
configure the device to shutdown the regulator if an extended
over current event is detected, which requires a toggle of the
Enable pin to return the device to normal operation. Contact
Semtech Marketing for specific information.)
Thermal Shutdown
If the die temperature exceeds 170°C (typical), the VSW
outputs will tri-state to protect the device from damage. The
PG and all other protection circuitry stay active to inform
the system of the failure mode. Once the device cools to
160°C (typical), the device will start up again, following the
normal soft start sequence. If the die again reaches 170°C, the
shutdown/restart sequence will repeat.
Reference Soft Start
The reference in this device is ramped at a rate of 4ms to
prevent the output from overshoot during startup. This ramp
restarts whenever there is a rising edge sensed on the Enable
pin. This occurs in both the fixed and adjustable versions.
During the soft start ramp, current limit is still active, and will
still protect the device in case of a short on the output.
Output Overvoltage
If the FB input exceeds 103% of the regulation voltage, the
VSW outputs will tri-state to protect the device from damage.
This check occurs at the start of each switching cycle. If it
occurs during the middle of a cycle, the switching for that
cycle will complete, and the VSW outputs will tri-state at the
beginning of the next cycle.
VCC Under-Voltage Lockout
The device is held in the off state until VCC reaches 4.5V
(typical). There is a 500mV hysteresis on this input, which
requires the input to fall below 4.0V (typical) before the device
will disable.
Transient Response
TS30011/12/13 has been designed to work under a wide range
of input and output voltages, supporting different values and
types of output capacitance. By design, the TS30011/12/13
has a lower control loop bandwidth. For designs with a high
slew rate load requirement, using a 1nF feed-forward capacitor
CFF (Figure 23) in parallel with RTOP feedback resistor is recom-
mended. A typical response is shown in Figure 22.

Typical Application Schematic
Figure 23: TS30011/12/13 Application Schematic
A minimal schematic suitable for most applications is shown on page 1. Figure 23 includes optional components that may be
considered to address specific issues as listed in the External Component Selection section.
PCB Layout
For proper operation and minimum EMI, care must be taken during PCB layout. An improper layout can lead to issues such as poor
stability and regulation, noise sensitivity and increased EMI radiation. (Figure 24) The main guidelines are the following:
• provide low inductive and resistive paths for loops with high di/dt or high dV/dt,
• provide low capacitive paths with respect to all the other nodes for traces with high di/dt or high dV/dt,
• sensitive nodes not assigned to power transmission should be referenced to the analog signal ground (GND) and should
always be separated from the power ground (PGND).
The negative ends of CBYPASS, COUT and the Schottky diode DCATCH (optional) should be placed close to each other and connected
using a wide trace. Vias must be used to connect the PGND node to the ground plane. The PGND node must be placed as close as
possible to the TS30011/12/13 PGND pins to avoid additional voltage drop in traces.
The bypass capacitor CBYPASS (optionally paralleled to a 0.1µF capacitor, CBYPASS2) must be placed close to the VCC pins of
TS30011/12/13.
The inductor must be placed close to the VSW pins and connected directly to COUT in order to minimize the area between the VSW
pin, the inductor, the COUT capacitor and the PGND pins. The trace area and length of the switching nodes VSW and BST should be
minimized.
For the adjustable output voltage version of the TS30011/12/13, feedback resistors RBOT and RTOP are required for Vout settings
greater than 0.9V and should be placed close to the TS30011/12/13 in order to keep the traces of the sensitive node FB as short
as possible and away from switching signals. RBOT should be connected to the analog ground pin (GND) directly and should never
be connected to the ground plane. The analog ground trace (GND) should be connected in only one point to the power ground
(PGND). A good connection point is under the TS30011/12/13 package to the exposed thermal pad and vias which are connected
to PGND. RTOP will be connected to the VOUT node using a trace that ends close to the actual load.
For fixed output voltage versions, RBOT and RTOP are not required and the FB pin should connect directly to VOUT.

External Component Selection
The 1MHz internal switching frequency of the TS30011/12/13 facilitates low cost LC filter combinations. Additionally, the fixed
output versions enable a minimum external component count to provide a complete regulator with only 4 external components:
an input bypass capacitor, an inductor, an output capacitor, and the bootstrap capacitor. The internal compensation is optimized
for a 44uF output capacitor and a 4.7uH inductor.
For best performance, a low ESR ceramic capacitor should be used for CBYPASS. If CBYPASS is not a low ESR ceramic capacitor, a 0.1uF
ceramic capacitor should be added in parallel to CBYPASS.
The minimum allowable value for the output capacitor is 33uF. To keep the output ripple low, a low ESR (less than 35mOhm)
ceramic is recommended. Multiple capacitors can be paralleled to reduce the ESR.
The inductor range is 4.7uH +/-20%. For optimal over-current protection, the inductor should be able to handle up to the
regulator current limit without saturation. Otherwise, an inductor with a saturation current rating higher than the maximum IOUT
load requirement plus the inductor current ripple should be used.
For high current applications, the optional Schottky diode DCATCH improves overall efficiency and reduces heat. It is up to the user
to determine the cost/benefit of adding this additional component in the user’s application. The diode is typically not needed.
For the adjustable output versions, the output voltage can be adjusted by sizing RTOP and RBOT feedback resistors. The equation for
the output voltage is

Note 1: The voltage divider resistor values are calculated for an output voltage of 2.5V. For fixed output versions, the FB pin is connected directly to VOUT.
For the adjustable version, the ratio of VCC/Vout cannot exceed 16.
RPLP is only required when the Power Good signal (PG) is utilized.
Thermal Information
TS30011/12/13 is designed for a maximum operating junction temperature Tj of 125°C. The maximum output power is limited by
the power losses that can be dissipated over the thermal resistance given by the package and the PCB structures. The PCB must
provide heat sinking to keep the TS30011/12/13 cool. The exposed metal on the bottom of the QFN package must be soldered to
a ground plane. This ground should be tied to other copper layers with multiple thermal vias. Adding more copper to the top and
the bottom layers and tying this copper to the internal planes with vias can reduce thermal resistance further. For a hi-K JEDEC

board and 13.5 square inch of 1 oz Cu, the thermal resistance from junction to ambient can be reduced to θJA = 38°C/W. The
power dissipation of other power components (catch diode, inductor) cause additional copper heating and can further increase
what the TS30011/12/13 sees as ambient temperature.
