The TPS6512x DC-DC converter supplies all three voltages required by amorphous-silicon (a-Si) and low-temperature poly-silicon (LTPS) TFT-LCD displays. The compact layout of the TPS6512x uses a single inductor to generate independently-regulated positive and negative outputs. A free-running variable peak current PWM control scheme time-multiplexes the induct.
