LMR33620BQRNXRQ1 is a 1.4 MHz, 2 A automotive synchronous buck regulator for converting 3.8 V to 36 V rails to an adjustable 1 V to 24 V output.

Best for

  • AEC-Q100 Grade 1 automotive buck conversion
  • Compact 2 A point-of-load rails
  • Automotive infotainment and telematics power

Avoid if

  • An output current above 2 A is required
  • A fixed output voltage without external feedback components is preferred
  • A tightly fixed switching frequency is required at all light-load conditions

Check before use

  • Verify operation across the complete VIN and VOUT range
  • Confirm inductor saturation current against device current limits
  • Validate thermal performance on the production PCB
  • Follow the split VIN/PGND capacitor layout guidance for the RNX package
