Description
STEVAL-ILL006V1
This board represents a low cost, high efficiency,
high brightness multiple LED driver based on the
integrated off-line switching regulator VIPer22A-E.
The board is an off-line, constant current power
supply capable of driving from 2 to 8 LEDs in
series operating from universal mains input. The
output current can be selected for compatibility
with 1 W, 3 W and 5 W LEDs with a total output
power of up to 10 W.
