Non-Synchronous PWM Boost Controller for LED Driver

FP7208XR-G1/FP7208AXR-G1/FP7208BXR-G1

General Description

The FP7208 is boost topology switching regulator for LED driver. It provides built-in gate driver

pin for driving external N-MOSFET. The non-inverting input of error amplifier connects to a 0.2V

reference voltage. It has programmable soft start time set by external capacitor, and over voltage

protection set by external resistor. The LED current can be adjusted by an external signal connecting

to the EN pin. EN pin accepts either a DC voltage or a PWM signal. The PWM signal filter components

are contained within the chip.
