FP7171 Overview
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.
