synchronous buck80 V input2 A outputFPWMspread spectrumindustrial power

LMR38020FSDDAR is a wide-input 2 A synchronous buck regulator intended for industrial DC power rails requiring forced-PWM operation and spread-spectrum EMI reduction.

Best for

  • Industrial wide-input DC/DC rails
  • Applications needing constant-frequency FPWM behavior
  • Designs requiring spread-spectrum EMI reduction

Avoid if

  • Applications where light-load PFM efficiency is required
  • Systems requiring output voltage above input voltage
  • Layouts without adequate thermal copper and exposed-pad grounding

Check before use

  • Validate input surge protection for the actual system
  • Set switching frequency with the RT/SYNC network
  • Confirm output capacitor effective capacitance under DC bias
  • Verify thermal performance at full load
