Voltage Regulators - DC DC Switching Regulators

2 A buck regulatorAEC-Q1001.4 MHz36 V inputadjustable outputVQFN-HR

LMR33620BQRNXTQ1 is an automotive-qualified 2 A synchronous buck regulator for converting 3.8 V to 36 V rails to an adjustable 1 V to 24 V output at a 1.4 MHz nominal switching frequency.

Best for

  • Automotive 12 V or higher voltage rails requiring a compact 2 A buck stage
  • Telematics, infotainment, instrument-cluster, and USB charging power rails

Avoid if

  • A fixed 3.3 V or 5 V output variant is specifically required
  • The application requires a guaranteed constant switching frequency at light load

Check before use

  • Confirm output voltage, current, and thermal requirements
  • Check inductor saturation current against device current limits
  • Validate EMI and loop stability using the intended PCB layout
