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.
■ Switching Frequency 750kHz (AVDD, VIO).
■ Switching Frequency 1MHz (VCORE, HAVDD).
Applications
■ TFT-LCD panel
