STEVAL-TLL007V1
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 STEVAL-
TLL007V1 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.
