FP7171 Datasheet | Feeling Technology

Universal High Brightness LED Driver General Description The FP7171 is an open loop, current mode, control LED driver IC. The FP7171 can be programmed to operate in either a constant frequency or constant off-time mode. It includes an 15 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 FP7171 includes a PWM dimming and 0 - 250mV linear dimming input which can be used for linear dimming of the LED current. The FP7171 is ideally suited for buck LED drivers. Since the FP7171 operates in open loop current mode control, the controller achieves good output current regulation without the need for any...
