Quick start guide for the
STEVAL-TLL005V1 power flash demonstration board
Introduction
This document provides the basic settings and instructions for using the STEVAL-TLL005V1
power flash demonstration board based on the STCF03. The STCF03 is a high efficiency
power supply solution to drive a single flash LED in camera phones, PDAs and other hand-
held devices. The STCF03 is a buck-boost converter to provide the proper LED current
control over all possible battery voltage and output voltage conditions. All functions of the
device are controlled by a microcontroller through an I²C interface.
The STEVAL-TLL005V1 consists of both a motherboard and a daughterboard connected
together (STEVAL-TLL004V1 for the daughterboard only).
