More Information

The TPS65146 offers a very compact 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 Vcom buffer driving the LCD backplane. In addition to that, a gate voltage shaping block is integrated for VGH, modulating the signal (into VGHM) with high flexibility by using a logic input VFLK and an external discharge resistor connected to RE pin. Also, an external discrete negative charge pump can be set using the boost converter of the TPS65146 to generate VGL (Gate Driver Low voltage). The integrated reset function together with the LCD discharge function available in the TPS65146 provide the signals enabling the discharge of the LCD TFT pixels when powering-off. The device includes safety features like overvoltage protection (OVP), as well as thermal shutdown.
