FP7172

FP7172 Universal High Brightness LED Driver General Description The FP7172 is an open loop, current mode, control LED driver IC. The FP7172 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 FP7172 is ideally suited for buck LED drivers. Since the FP7172 operates in open loop current mode control, the controller achieves good output current regulation without the need for any loop compensation. The FP7172 is available in the small footprint SOT23-6L package to fit in space-saving PCB layout for miscellaneous application fields.
