More Information
The TPS65148 offers a compact power supply solution designed to supply the LCD bias voltages required by TFT (Thin Film Transistor) LCD panels running from a typical 5 V supply rail. The device integrates a high power step-up converter for VS (Source Driver voltage), an accurate voltage rail using an integrated LDO to supply the Gamma Buffer (VREG_O) and a Vcom buffer driving the LCD backplane. In addition to that, a gate voltage shaping block is integrated. The VGH signal (Gate Driver High voltage) supplied by an external positive charge pump, is modulated into VGHM with high flexibility by using a logic input VFLK and an external discharge resistor connected to the RE pin. Also, an external negative charge pump can be set using the boost converter of the TPS65148 to generate VGL (Gate Driver Low voltage). The integrated reset function together with the LCD discharge function available in the TPS65148 provide the signals enabling the discharge of the LCD TFT pixels when powering-off. The device includes safety features like overcurrent protection (OCP) and short-circuit protection (SCP) achieved by an external input-to-output isolation switch, as well as overvoltage protection (OVP) and thermal shutdown.
