EVL130W-STRLIG(1): 48V @ 2.7A, 85 ~ 305 VAC

Manufacturer: STMicroelectronics

* For Constant Current, the board must be modified as described on page 8 of the user guide. * Streetlight applications require that the power supply designed to power an LED lamp must have high efficiency and at least an equivalent lifetime in order to guarantee maintenance-free operation during the life of the LED.

EVL6562A-LED: 350mA @ 45V Max, 36 ~ 60V in

Manufacturer: STMicroelectronics

Whenever a lighting application, such as street lighting for example, requires an elevated number of LEDs, there are basically two solutions: the first is to connect all the diodes in series in a single "string"; the second is to place several strings in parallel with fewer elements in each one.

CAT4201AGEVB: 350mA @ 20V Max, 6.5 ~ 28V in

Manufacturer: ON Semiconductor

The CAT4201 is a high efficiency step-down LED driver from Catalyst Semiconductor. This device is designed to drive high brightness LEDs up to 350mA from a power supply up to 28V. The LED brightness is controlled by a single resistor from the RSET pin to GND. Analog dimming and idle mode control are available through the CTRL input. An external circuit is provided on the CAT4201AEVB for PWM dimmin…

STEVAL-ILL016V2: 350mA, 700mA, 1A @ 40V Max, TRIAC

Manufacturer: STMicroelectronics

This application note presents a low-cost driver for LEDs that is compatible with TRIAC phase-control dimmers. The design gives luminaire manufacturers a low-cost, commonly available dimming option for home fixtures. A side benefit is that, when not wired to a dimmer, the unit's power factor is over 0.9. The design is based on the L6562A transitionmode PFC controller driving a single stage PFC-fl…

LM3409HVEVAL: 1.5A @ 42V Max, 48V in

Manufacturer: Texas Instruments

This evaluation board showcases the LM3409HV PFET controller for a buck current regulator. It is designed to drive 12 LEDs (VO = 42V) at a maximum average LED current (ILED = 1.5A) from a DC input voltage (VIN = 48V). The switching frequency (fSW = 400 kHz) is targeted for the nominal operating point, however fSW varies across the entire operating range.
