Voltage Regulators - DC DC Switching Regulators

36 V buck regulator2 A5 V output1 MHzsynchronousVQFN-HRPGOOD

LMR43620MB5RPER is a compact 36 V, 2 A synchronous buck regulator intended for a 5 V rail, with fixed 1 MHz operation and MODE/SYNC control.

Best for

  • Compact industrial 5 V rails
  • 36 V nominal input systems
  • Applications requiring PGOOD
  • Fixed-frequency or synchronized power stages

Avoid if

  • Input voltage can exceed 42 V without suitable protection
  • The required continuous load exceeds 2 A
  • The PCB cannot provide adequate heat spreading

Check before use

  • Confirm inductor saturation current against the 3.9 A maximum high-side peak current limit.
  • Use the required local ceramic capacitors and account for DC-bias derating.
  • Do not leave EN or MODE/SYNC floating.
