CM501 LCD Driver

Description

The CM501 generates all the supply rails for thin-film transistor (TFT) liquid-crystal display (LCD) panels in TVs and Monitors. It includes boost and buck regulators, VGH and VGL charge pump regulators, gate pulse modulator (GPM) , HV LDO, voltage detector (XAO) and VCOM OP. The CM501 can support input voltage from 8V to 14V and is optimized for LCD TV panel and LCD monitor applications running directly from 12V supply.
