80 V input1 A buck converterSynchronous rectificationPFMSpread spectrumSO PowerPAD

LMR38010SDDAR is a wide-input 1 A synchronous buck converter for industrial DC rails up to 80 V, using PFM light-load operation and integrated spread spectrum.

Best for

  • Wide-input industrial buck conversion
  • Low standby-current PFM power rails
  • Applications requiring spread-spectrum EMI reduction

Avoid if

  • Output current exceeds 1 A continuously
  • A fixed switching frequency at light load is required
  • The input supply can fall below the output without reverse-current protection

Check before use

  • Confirm output capacitor effective capacitance at DC bias
  • Use an inductor that does not saturate under current-limit conditions
  • Place input bypass capacitors close to VIN and GND
  • Connect the exposed thermal pad to system ground with thermal vias
