Capacitors

TPS628303ARZER is a 3 A adjustable synchronous buck regulator for low-voltage point-of-load rails from a 2.25 V to 5.5 V source.

Best for

  • 3 A point-of-load rails
  • ASIC, SoC, and MCU supplies
  • Compact low-voltage buck designs

Avoid if

  • Input voltage can exceed 5.5 V
  • A latch-off overcurrent/overvoltage response is required
  • The system requires a fixed output voltage without an external feedback divider

Check before use

  • Verify effective output capacitance after DC-bias derating.
  • Keep VIN, SW, inductor, and capacitor power loops short in the PCB layout.
  • Do not leave EN or MODE floating.
