Voltage Regulators - DC DC Switching Regulators

synchronous buck25 A4 V to 19 V inputLQFN-CLIPremote sensedual-phase capable

TPS543B20RVFT is a 25 A integrated synchronous buck regulator for 4 V to 19 V point-of-load rails, with programmable output voltage, remote sensing, and optional two-phase operation.

Best for

  • High-current point-of-load rails
  • Server, switch, router, FPGA, ASIC, and SoC power

Avoid if

  • Input voltage exceeds 19 V
  • The design cannot provide the required thermal pad and power-ground layout

Check before use

  • Verify output-current thermal capability in the final PCB
  • Place mandatory high-frequency PVIN bypassing close to the IC
  • Route RSP and RSN as a Kelvin differential sense pair
