Description

The STEVAL-TLL008V1 demonstration board is a

flash LED driver using the STCF04 device, which

is a buck-boost converter with an I

dedicated to charging a SuperCap.

All LEDs with a forward voltage range from 2.5 V

to 5 V are compatible with the STCF04. The

forward voltage spread of any selected LED must,

however, be within this range (2.5 V to 5 V). It is

possible to set the level of the LED current in

Flash mode and Torch mode by setting the

dimming registers. The maximum level of the LED

current in Flash mode can be set by changing the

external flash resistor.
