General Description
The FP7209 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 0.25V
reference voltage. There are three functions to protect system circuit like UVP, OVP and OCP. The
LED current can be adjusted by an external signal connecting to the DIM pin. DIM pin accepts either a
DC voltage or a PWM signal. The PWM signal filter components are contained within the chip. Current
mode control and external compensation network make is easy and flexible to stabilize the system.
The FP7209 is available in the small footprint SOP-8L(EP) package to fit in space-saving PCB
layout for application fields.
