General Description

The STCF01 is a dedicated IC designed to drive two, three, or four white, cell phone camera flash LEDs with constant current.

The step-up (boost) converter input is connected directly to the battery, and its converter output voltage is automatically determined using current feedback-based duty cycle control.

The STCF01 has a dedicated pin for two levels of www.DataSheet4U.com LED current selection.
