LMR51625XFDDCR

Component

2.5 A4.3 V to 60 V400 kHzFPWMSynchronous buckSOT-23-THN

LMR51625XFDDCR is a 2.5A, 400kHz forced-PWM synchronous buck regulator for converting 4.3V to 60V inputs to an adjustable 0.8V to 30V output.

Best for

  • Wide-input industrial buck supplies
  • Applications requiring fixed 400kHz operation
  • Low-ripple rails requiring forced-PWM behavior

Avoid if

  • A PFM light-load operating mode is required
  • The application needs more than 2.5A continuous output current
  • Thermal conditions cannot be validated on the final PCB

Check before use

  • Verify input transients remain within the 63V VIN absolute maximum rating.
  • Confirm inductor saturation current exceeds the applicable current-limit level.
  • Validate junction temperature remains below 150 °C in the final layout.
