TPS65124 - SINGLE-INDUCTOR QUADRUPLE-OUTPUT TFT LCD POWER SUPPLY

Download the TPS65124 datasheet PDF. This datasheet also covers the TPS65120 variant, as both devices belong to the same single-inductor quadruple-output tft lcd power supply family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key Features

  • Main Output, VMAIN.
  • Adjustable Voltage, 3.0 V to 5.6 V/25 mA.
  • Post-Regulated for Low Ripple (5mVPP).
  • ±0.8% Typical Accuracy.
  • Efficiency up to 83%.
  • Positive Output, VGH.
  • Adjustable Voltage up to 20 V/2 mA.
  • ±3% Typical Accuracy.
  • Negative Output, VGL.
  • Adjustable Voltage down to -18 V/2 mA.
  • ±3% Typical Accuracy.
  • Auxiliary 1.8 V/3.3 V Linear Regulator.
  • Automatic or Programmable Power.
