Description

This demonstration board implements a flash LED driver using the STCF06 device, which is a buck-boost current mode converter with an I2C interface.

The flash LED driver STCF06 has a high operating frequency (1.8 MHz) which allows the usage of small external components.

The demonstration board is designed for driving a single LED with a forward voltage range from 2.7 to 5 V.

For easy connection to a PC, the STEVALTLL006V1 uses a μPSD-based motherboard used as a bridge.

The STCF06 motherboard uses an USB human interface device to communicate with the PC. It is not necessary to install a driver, if the operating system in use is capable of enumerating USB human interface devices.

Features
■ Buck-boost DC-DC converter
