MP3371 Description
The MP3371 is a synchronous boost converter with eight current channels designed to drive WLED arrays for LCD panels in tablets and notebook backlighting applications. The MP3371 uses peak current control mode and pulse-width modulation (PWM) control to maintain boost converter regulation. The MP3371 employs a standard I2C digital interface to set the operation mode, switching frequency, full-scale current for each...
