EV3399EF-00A

The EV3399EF-00A is an evaluation board for the MP3399EF, a 12 LED channels step-up converter designed for large liquid-crystal displays that employ an array of LEDs as the light source. The board builds with two MP3399EF in parallel to drive 24 strings LEDs with 60mA maximum current.

The MP3399 uses external power mosfet and internal current mode, fixed frequency architecture and includes current ballast in each string terminal, which achieves 2.5% current regulation accuracy between strings. Low feedback voltage at each LED string help reduce power loss and improve efficiency.

The MP3399 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.
