Power Management (PMIC)

36 V buck regulator2 A synchronous converterAdjustable frequency5 V fixed or adjustableVQFN-HR

LMR43620R5RPER is a compact 2 A synchronous buck regulator for industrial input rails up to 36 V, with an RT-set switching frequency from 200 kHz to 2.2 MHz.

Best for

  • Compact industrial 5 V power rails
  • Factory and building automation
  • Applications requiring adjustable switching frequency

Avoid if

  • Required continuous output current exceeds 2 A
  • Input voltage exceeds 36 V during normal operation
  • A fixed-frequency MODE/SYNC variant is required

Check before use

  • Confirm 42 V input transient exposure remains within the absolute maximum rating
  • Confirm output voltage and frequency configuration
  • Measure junction temperature and load transient response on the final PCB
