DESCRIPTION
The EV3388EY-00A is an evaluation board for the
MP3388EY, 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.
