Application note

Driver for double flash LED with IC interface

Introduction
This application note is dedicated to the design of a flash LED driver using the STCF05
device, which is a boost current mode converter with an IC interface and internal current
source. The schematic, functional description, recommendations for PCB layout and
external components selection are also discussed in this application note. The STCF05
device is designed to drive two LEDs in series with a total forward voltage from 5.3 V to
10.2 V.
