MPQ3367 Overview
The MPQ3367 is a step-up converter with 6 channel current sources, designed to drive the white LED arrays as backlighting in small-to-midsize LCD panels. The MPQ3367 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.
