BM81004MUV

Datasheet Power supply IC series for TFT-LCD panels 12V Input Multi-Channel System Power Supply IC BM81004MUV General Description BM81004MUV is a system power supply for TFT-LCD panels used for liquid crystal TVs. This IC is incorporated with Negative and Positive charge pump controller 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). ■ Step-down DC/DC converter 3(HAVDD). (Synchronous rectification). ■ Positive charge pump controller (VGH). ■ Negative charge pump controller (VGL). ■ Gate Pulse Modulation (GPM) function. ■ High Voltage LDO (50mA) ■ 10 bit DAC-controlled Gamma Amplifier 4ch ■ 8 bit DAC-controlled VCOM Amplifier ■ Output voltage control by I2C. ■ Built-in EEPROM. ■ Sw...
