FP7209 Non-Synchronous PWM Boost Controller for LED Driver 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. It has programmable soft start time and switching frequency set by external capacitor and resistor. There are four functions to protect system circuit, such as UVP, OVP, SCP 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.
