60 V buck regulator3.5 A output400 kHz PFMSynchronous rectificationSpread spectrumSOT-23-THIN

LMR51635XDDCR is a compact 60 V synchronous buck regulator for adjustable rails up to 3.5 A. This X-version operates at 400 kHz in PFM mode and includes spread-spectrum operation.

Best for

  • Wide-input industrial DC rails
  • PLC, DCS, PAC, and smart-meter power
  • Compact adjustable supplies up to 3.5 A

Avoid if

  • A fixed switching frequency is mandatory at light load
  • The application cannot provide adequate PCB thermal area
  • Input transients exceed the specified 60 V operating range

Check before use

  • Verify duty-cycle and frequency-foldback behavior at minimum and maximum input voltage.
  • Use a 0.1 µF X5R or X7R bootstrap capacitor between CB and SW.
  • Keep input bypass capacitors close to VIN and GND, and keep the feedback path away from SW noise.
