    Description

    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 inductor between outputs. This control architecture operates at a pseudo-fixed-frequency to provide fast response to line and load transients while maintaining a relatively constant switching frequency and high efficiency over a wide range of input and output voltages. Due to the high switching frequency capability of the device, inexpensive and ultra-thin 8.2 or 10 µH inductors can be used.
