FP8013
5V, 3A, 1.5MHz Buck Constant Current Switching Regulator for White LED
General Description
The FP8013 is a PWM control buck converter designed to provide a simple, high efficiency solution for driving high power LEDs. With a 0.1V reference voltage feedback control to minimize power dissipation, an external resistor sets the current as needed for driving various types of LEDs. The FP8013 includes both high low side switch to realize high efficiency and compact PCB layout. To extend battery life for portable application, 100% duty cycle is supported for low-dropout operation. Other features include thermal shutdown, cycle-by cycle current limit and over current protection
