MPQ3364-AEC1 Four-Channel WLED Driver

Monolithic Power Systems (MPS) MPQ3364-AEC1 Four-Channel WLED Driver is a configurable, fixed-frequency step-up converter designed to drive white LED arrays as backlighting for LCD panels. The MPQ3364-AEC1 uses peak current mode as its PWM control architecture to regulate the boost converter. Four current source channels are applied to the LED cathode to adjust LED brightness. The MPQ3364 regulates the current in each LED string to the value set by an external current setting resistor, with 2.5% current regulation accuracy between strings.
