The EV3388DR-01A is an evaluation board for the MP3388DR, a step-up converter designed for large liquid-crystal displays that employ an array of LEDs as the light source. It can drive up to 8 strings in parallel and 10 LEDs per string.
The MP3388 uses internal switch current mode, fixed frequency architecture and includes current ballast in each string terminal, which achieves ±3% current regulation accuracy between strings. Low feedback voltage at each LED string help reduce power loss and improve efficiency.
The MP3388 has multiple features to protect the converter from fault conditions, including under-voltage lockout, current limiting, over voltage, short LED, open LED and thermal shut-down protection.
The MP3388 is available in small QFN24 (4mmx 4mm), TSSOP28 and SOIC28 package.
