synchronous buck5 A regulator3.8 V to 28 V inputPFMFCCMspread spectrumVQFN-HR

TPS54538RQFR is a compact 5 A synchronous buck regulator for 3.8 V to 28 V input rails, offering selectable light-load behavior and spread-spectrum EMI reduction.

Best for

  • Compact 5 V, 12 V, or similar intermediate-voltage rails
  • Distributed power systems
  • Applications requiring selectable light-load efficiency or fixed-frequency operation

Avoid if

  • Applications requiring more than 5 A continuous output current
  • Designs needing a guaranteed fixed switching frequency while configured for PFM
  • Systems operating outside the 3.8 V to 28 V input range

Check before use

  • Verify output-current derating over temperature
  • Keep the VIN-GND input capacitor loop short and low inductance
  • Select MODE resistance for the intended PFM/FCCM, SS/PG, and spread-spectrum behavior
