MP3378E Overview
The MP3378E is a one-chip solution specially designed for monitor applications. The MP3378E includes a step-up WLED controller with four current channels for backlighting, and a high-efficiency buck converter for internal bus voltage or standby power. The 4-string WLED controller drives an external MOSFET to boost up the output voltage from the input supply.
