Overview

MP3378E 4-Channel WLED Controller with High-Efficiency Buck Converter DESCRIPTION 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.
It regulates the current in each LED string to the programmed value set by an external current setting resistor.
It supports both analog and PWM dimming independently to meet special dimming mode requests.
Full protection features for the WLED controller i...
