LMR51410XFDBVR is a 1 A, 400 kHz FPWM synchronous buck regulator for regulated industrial rails from 4 V to 42 V inputs.

Best for

  • Industrial auxiliary rails
  • PLC, DCS, and PAC power rails
  • Smart meter power supplies
  • Fixed-frequency low-ripple converter designs

Avoid if

  • A PFM light-load efficiency mode is required
  • Output current exceeds 1 A continuous capability
  • A lower switching frequency or externally compensated control loop is required

Check before use

  • Confirm output current derating at high ambient temperature
  • Confirm the 400 kHz FPWM variant is desired
  • Verify input transient exposure remains within device limits
  • Review PCB thermal copper and high-current loop layout
