DESCRIPTIONThe TPS65148 offersa compact power supply solution designedto supply the LCD bias voltages required by
TFT (Thin Film Transistor) LCD panels running froma typical5V supply rail. The device integratesa high power
step-up converter for VS (Source Driver voltage), an accurate voltage rail usingan integrated LDOto supply the
Gamma Buffer (VREG_O) anda Vcom buffer driving the LCD backplane.In additionto that,a gate voltage shaping
blockis integrated. The VGH signal (Gate Driver High voltage) suppliedby an external positive charge pump,is
modulated into VGHM with high flexibility by usinga logic input VFLK and an external discharge resistor
connectedto the RE pin. Also, an external negative charge pump can be set using the boost converterof the
TPS65148to generate VGL (Gate Driver Low voltage). The integrated reset function together with the LCD
discharge function availablein the TPS65148 provide the signals enabling the dischargeof the LCD TFT pixels
when powering-off. The device includes safety features like overcurrent protection (OCP) and short-circuit
protection (SCP) achievedbyan external input-to-output isolation switch,as wellas overvoltage protection (OVP)
and thermal shutdown.
