TPS54020RUWR is a 10 A synchronous buck regulator for compact, high-current point-of-load rails. It supports split VIN/PVIN rails, adjustable switching frequency, synchronization, soft start, and selectable overcurrent behavior.

Best for

  • High-current point-of-load rails
  • FPGA, SoC, DSP, and processor supplies
  • Systems needing adjustable frequency or clock synchronization

Avoid if

  • The control supply is below 4.5 V
  • The required output current exceeds 10 A continuous capability
  • PCB area or thermal design cannot support a high-current VQFN power stage

Check before use

  • Confirm VIN is 4.5 V to 17 V and PVIN is 1.6 V to 17 V.
  • Use the required 0.1 µF BOOT-to-PH capacitor.
  • Validate loop stability with the chosen output capacitors and ILIM setting.
