STEVAL-ILL019V1

STEVAL-ILL019V1 32 W offline RGGB LED driver with individual LED channel brightness regulation Data brief Features ■ Line voltage range: 88 to 265 VAC ■ 4-channel LED driver ■ Constant LED current: 350 mA ■ Load: 5 to 13 LEDs per channel ■ Rated output power: 32 W (wide voltage range) ■ Rated output power: 42 W (EU voltage range) ■ Isolated SMPS ■ Individual RGGB brightness regulation ■ EN55015 and EN61000-3-2 compliant ■ PCB: double-side, 145 x 75 x 27 mm ■ RoHS compliant STEVAL-ILL019V1 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).
