LP6283 Description
The LP6283 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 V OP. The LP6283 supports input voltage from 8V to 14V and is optimized for LCD TV panel and LCD monitor applications running directly from 12V supply.
