BM81110MUW - Rohm

BM81110MUW 12V Input Multi-Channel System Power Supply

BM81110MUW is a system power supply for TFT-LCD panels used for liquid crystal TVs. This IC is incorporated with Negative and Positive charge pump controllers and Gate Pulse Modulation (GPM) function. It also features built-in EEPROM to contain each setting voltage, soft start time, etc. Features ■ Step-up DC/DC converter (AVDD) (Synchronous rectification, .
