MONOLITHIC POWER SYSTEMS (MPS) MPQ3369GF-AEC1-P Datasheet & Stock

The MPQ3369-AEC1 is a step-up converter with six channel current sources, designed to drive white LED arrays as backlighting in small-to-mid-size LCD panels. The MPQ3369-AEC1 uses peak current mode as its PWM control architecture to regulate the boost converter. Six channel current sources are applied into the LED cathode to adjust the LED brightness. It regulates the current in each LED string to the value set via an external current-setting resistor, with 2.5% current regulation accuracy between strings. The MPQ3369-AEC1 employs a low on-resistor MOSFET and a low headroom voltage, designed for higher efficiency. It has a standard I2C digital interface for ease of use.
