BM81110MUW

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. Features ■ Step-up DC/DC converter (AVDD) (Synchronous rectification, built-in load switch) ■ Step-down DC/DC converter 1 (VIO) (Non-synchronous rectification) ■ Step-down DC/DC converter 2 (VCORE) (Synchronous rectification) ■ Step-down DC/DC converter 3 (HAVDD) (Synchronous rectification) ■ Positive charge pump controller (VGH) ■ Negative charge pump controller (VGL) ■ Gate Pulse Modulation (GPM) function ■ Output voltage control by I2C ■ Built-in EEPROM ■ Switching Frequency 750kHz (AVDD, VIO) ■ Switching Frequency 1MHz (VCORE, HAVDD) Application...
