STEVAL-TLL007V1 High-power LED driver demonstration board for dual flash with I²C interface based on the STCF05
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.
