This product is 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.
The document describes the STEVAL-ILLOO6V1, a low-cost and high-efficiency multiple LED driver board. It is designed to drive from 2 to 8 LEDs in series using an integrated off-line switching regulator, specifically the VIPer22A-E.
This evaluation board operates as a constant current power supply compatible with universal mains input voltages ranging from 90 to 264 VAC at 50/60 Hz. The output current is selectable for compatibility with 1 W, 3 W, and 5 W LEDs, supporting total output powers up to 10 W.
