TPS51285BRUKT

Voltage Regulators - Linear + Switching

dual buck controller5 V rail3.3 V railD-CAPWQFN-20notebook power

TPS51285BRUKT is a dual synchronous buck-controller IC for 5 V and 3.3 V notebook or tablet power rails. It requires external MOSFETs, inductors, output capacitors, feedback dividers, and current-limit setting resistors.

Best for

  • Notebook power rails
  • Tablet power rails
  • Dual 5 V and 3.3 V buck supplies

Avoid if

  • A fully integrated regulator without external MOSFETs is required
  • The output network must use ceramic capacitors only

Check before use

  • Output capacitor ESR and loop stability
  • MOSFET RDS(on) and overcurrent-limit calibration
  • Input and switch-node voltage ratings
  • Thermal-pad connection to ground plane
