Power Management (PMIC)

1 A buck regulator4 V to 65 V input400 kHzFPWMSOT-23-6Synchronous rectification

LMR51610XFDBVR is a compact 1 A synchronous buck regulator for wide-input industrial rails where fixed 400 kHz FPWM operation and low light-load output ripple are required.

Best for

  • Wide-input industrial buck rails
  • Low-ripple fixed-frequency power rails
  • Compact 1 A point-of-load conversion

Avoid if

  • Input voltage can exceed the 65 V operating limit without suitable transient protection
  • A larger thermal package is required for sustained high-temperature operation
  • Pulse-frequency modulation is required for best light-load efficiency

Check before use

  • Check maximum junction temperature with the actual PCB copper area.
  • Use a 100 nF X5R or X7R bootstrap capacitor between CB and SW.
  • Place the input bypass capacitor directly near VIN and GND.
