80 V buck regulator3.3 V fixed output2.5 AAEC-Q100 Grade 1FPWMspread spectrumWSON-12

LMR38025FS3QDRRRQ1 is an automotive AEC-Q100 Grade 1 synchronous buck regulator for fixed 3.3 V rails from wide 4.2 V to 80 V inputs, with 2.5 A output capability and forced PWM operation.

Best for

  • Automotive 3.3 V auxiliary rails
  • 48 V mild-hybrid ECU supplies
  • Battery-management electronics
  • Motor-control support rails

Avoid if

  • A variable output voltage is required
  • The input may exceed the specified voltage ratings without suitable surge protection
  • The application cannot provide adequate PCB thermal dissipation

Check before use

  • Input-transient and surge protection design
  • Output capacitor effective capacitance and loop stability
  • Inductor saturation-current rating
  • WSON exposed-pad grounding and thermal vias
