MP3372 Overview
The MP3372 is a synchronous boost converter with eight current channels designed to drive WLED arrays for LCD panels in tablets and notebook backlighting applications. The MP3372 uses peak current mode and pulsewidth modulation (PWM) control to regulate the boost converter. The device employs a standard I2C digital interface to set the operation mode, switching frequency, full-scale current, synchronous or...
