STEVAL-TLL005V1 power flash demonstration board
based on the STCF03 and ST7
Introduction
This document describes the functionality of the STEVAL-TLL005V1 power flash
demonstration board based on STCF03 high power white LED driver and the ST7 8-bit
microcontroller. The STCF03 is a high efficiency power supply solution to drive a single flash
LED in camera phones, PDAs and other hand-held devices. It operates as a buck-boost
converter to guarantee proper LED current control in all possible battery voltage and output
voltage conditions. All functions of the device are controlled through an I
2
C interface via the
ST7 microcontroller. The STEVAL-TLL005V1 includes both the motherboard (Figure
1)
and
daughterboard (also available separately as STEVAL-TLL004V1,
Figure 2).
