DESCRIPTION
The EVQ3386-R-00A is an evaluation board for
the MPQ3386-R, 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 6 strings in parallel and 10 LEDs per
string.
The MPQ3386 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 MPQ3386 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 MPQ3386 is available in small QFN24
(4mmx 4mm) package.
