Datasheet

Power supply IC series for TFT-LCD panels

12V Input Multi-Channel

System Power Supply IC

BM81110MUW

General Description

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.
