Description
The STEVAL-ILL019V1 demonstration board
implements an isolated high-PF flyback converter
based on the L6562A transition-mode PFC
controller, capable of supplying 4 constant-current
outputs for 4 different RGGB LED modules.
Each module can contain 5 to 13 LEDs, with each
current channel set to 350 mA.
It is possible to choose between automatic color
change mode or manual color adjustment mode
(in the latter case some external components are
required).
