General Description

The FP7171DR-G1 is an open loop, current mode, control LED driver IC. The FP7171DR-G1 can be

programmed to operate in either a constant frequency or constant off-time mode. It includes an 8.5 -

450V linear regulator which allows it to work from a wide range of input voltages without the need for

an external low voltage supply. The FP7171DR-G1 includes a PWM dimming and 0 - 250mV linear dimming

input which can be used for linear dimming of the LED current. The FP7171DR-G1 is ideally suited for buck

LED drivers. Since the FP7171DR-G1 operates in open loop current mode control, the controller achieves

good output current regulation without the need for any loop compensation.
