TPS65148 Description
The TPS65148 offers a pact 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 V buffer driving the LCD backplane. In addition to that, a gate...
