FP7103

High Power DC/DC LED Driver

28V, 3A Buck Constant Current Switching Regulator for White LED.

 

General Description     

The FP7103 is a PWM control buck converter designed to provide a simple, high efficiency solution for driving high power LEDs. With a 0.25V reference voltage feedback control to minimize power dissipation, an external resistor sets the current as needed for driving various types of LEDs.
      The FP7103 includes a high current P-MOSFET to realize high efficiency and excellent transient characteristics. The PWM control circuit is able to change the duty ratio linearly from 0 up to 100%.
      Other features include user accessible EN/DIM pin for enabling and PWM dimming of LEDs, thermal shutdown, cycle-by cycle current limit and over current protection.
