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.
