LOWPOWER(微源半导体)Китай

The LP6262 is a programmable multi-functional power solution with integrated gamma buffers, VCOM1 buffer for TFT-LCD. It contains one boost converter controller (AVDD), one ISO MOSFET controller for AVDD power on sequence, one buck converter (VBK), one boost converter/positive charge pump regulator (VGH) with the temperature compensation, one inverting converter/negative charge pump regulator (VGL) with the temperature compensation, one negative regulators (VSS1), 14-CH gamma buffers, 1-CH VCOM1 buffer, 1-CH VCOM2 DAC. All channel output level and sequence can be programmable by I2C interface and integrated Multiple-Time Programmable (MTP) non-volatile memory. With its high current capabilities, the LP6262 is ideal for large screen LCD TV/MNT panel application with widely supply voltage range and also integrated complete protection functions including, OVP, UVP, OCP and OTP. The LP6262 available in a QFN6.5×4.5-46 pin package.
