General Description

The STCF03 is a high efficiency power supply solution to drive a single flash LED in camera phone, PDAs and other hand-held devices.

It is a buck - boost converter to guarantee a proper LED current control over all possible conditions of battery voltage and output voltage;

the output current control ensure a good current regulation over the forward voltage spread characteristics of the Flash LED.
