STEVAL-TLL008V2: 1.2A Flash Driver

Summary

The STEVAL-TLL008V2 demonstration board is a daughterboard working in conjunction with the STEVAL-TLL008V1 and was designed to demonstrate the performance of the STCF04 device, which is a buck-boost converter with an I2C interface 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.
