Description

This demonstration board is dedicated to the STCF05 flash LED driver IC, which is a boost current mode converter with an I2C interface and internal current source. The STCF05 is designed to drive two LEDs in series with a total forward voltage from 5.3 V to 10.2 V.

For easy connection to a PC, the STEVALTLL007V1 uses a μPSD-based motherboard used as a bridge.

The STCF05 motherboard uses a 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
■ Boost DC-DC converter with synchronous rectification
■ Drives two power white LEDs in series with a current up to 400 mA
■ Efficiency up to 85%
■ 3 passive components only
■ 24 mm2 PCB area only
■ 1.8 MHz fixed frequency PWM
