LCD power supplyTFT bias ICboost convertercharge pumpHTSSOP-24PowerPAD

TPS65145PWPR is an integrated LCD bias supply IC for TFT panels needing a boosted source-driver rail plus regulated positive and negative gate-drive rails.

Best for

  • TFT LCD bias supplies requiring multiple rails
  • Notebook and monitor LCD panels
  • LCD source-driver and gate-driver power rails

Avoid if

  • A higher boost-switch current limit is required
  • The application cannot accommodate external inductor, Schottky diode, capacitors, and compensation components
  • A fully integrated 3.3 V regulator without an external transistor is required

Check before use

  • VO1 output-current requirement at minimum VIN
  • Inductor saturation current and DCR
  • Charge-pump voltage headroom and load current
  • External linear-regulator transistor dissipation
  • Thermal-pad soldering and switching-current layout
