Product Summary
The TPS65123RGTR is a DC-DC converter supplies all three voltages required by amorphous-silicon (a-Si) andlow-temperature poly-silicon (LTPS) TFT-LCD displays. The compact layout of the TPS65123RGTR uses a singleinductor to generate independently-regulated positive and negative outputs. A free-running variable peak currentPWM control scheme time-multiplexes the inductor between outputs. The applications of the TPS65123RGTR include Small Form Factor a-Si and LTPS TFT LCD, Cell Phones, Smart Phones, PDAs, Pocket PCs, Portable DVD, Digital-Still Cameras, Camcorders, Handheld Instruments, Portable GPS, Car Navigation Systems.
