Triple Output Power Supply for TFT-LCD

The XC9516 series can offer three different power supplies to TFT-LCD panels. These power supplies consist of a step-up DC/DC converter for a source driver, positive and negative charge pumps for a gate driver.

This IC has power-on sequences to keep inrush current as small when output voltage rises. The step-up DC/DC output can be used as power-on sequences with adding a P-channel FET as external component. Also, the FET can shut down a path to the power input line when CE pin is low.
