PMIC for LCD TV / Monitor
General Description
The RT9955 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 RT9955 supports input voltage from 8V to 14V and is optimized for LCD TV panel and LCD monitor applications running directly from 12V supply.
The boost and buck regulators feature internal power MOSFETs and high frequency operation, allowing the use of small inductors and capacitors, for in a pact solution. Both switching regulators use fixed frequency,...
