The LP6281H 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 (VGH) with the temperature compensation, one inverting converter (VGL), one negative regulator (VSS), 14-CH gamma buffers, 2-CH VCOM buffer. 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 LP6281H is ideal for large screen LCD TV/MNT panel application with wide supply voltage range and also integrates complete protection functions including OVP, UVP, OCP and OTP.
The LP6281H is available in a QFN6.5x4.5-46 pin package.
