TPS65146 Description
The TPS65146 offers a very pact power supply solution designed to supply the LCD bias voltages required by TFT (Thin Film Transistor) LCD panels running from a typical 3.3 V or 5 V supply rail. The device integrates a step-up converter for VS (Source Driver voltage), a positive charge pump regulator for VGH (Gate Driver High voltage), a logic voltage rail using an integrated LDO and a V buffer driving the LCD...
