Voltage Regulators - DC DC Switching Regulators

PMBussynchronous buck35 Aintegrated MOSFETsremote sensecurrent telemetrytwo-phase capable

TPS546C23RVFT is an integrated 35 A synchronous buck regulator for digitally managed low-voltage rails requiring PMBus telemetry, configurable protection, and optional two-phase current sharing.

Best for

  • High-current processor, FPGA, ASIC, or memory power rails
  • Server, storage, switch, router, and base-station power systems
  • Digitally monitored rails using PMBus voltage, current, and temperature telemetry

Avoid if

  • Applications requiring input voltage above 18 V
  • Split-rail AVIN and PVIN operation
  • Very low-complexity rails where PMBus and high-current layout capability are unnecessary

Check before use

  • Verify the 4.5 V to 18 V input range covers all operating and transient conditions.
  • Set VOUT_SCALE_LOOP to match the external feedback-divider ratio.
  • Validate compensation and load-transient response on the final PCB.
  • Ensure adequate copper area, vias, and exposed-pad soldering for thermal performance.
