Description

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 vol
