Description

The STEVAL-TLL005V1 is a 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 phone,
PDAs and other hand-held devices. It is a buck­boost converter to guarantee a proper LED
current control over all possible conditions of
battery voltage and output voltage. All the
functions of the device are controlled through I
interface with microcontroller. The STEVAL­TLL005V1 include a mother plus a daughter
(STEVAL-TLL004V1 is the daughter only) boards.
