MP3367GF Overview
The MP3367 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 MP3367 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.
