Evaluation Tools

The EV3394EF-00A is an evaluation board for the MP3394EF, a step-up converter designed for liquid-crystal displays that employ an array of LEDs as the light source. It can drive up to 4 strings LEDs in parallel with 200mA/string maximum current.
The MP3394 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 MP3394 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.
