Universal High Brightness LED Driver
FP7172
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.
