LMR33620CQ5RNXRQ1 is an AEC-Q100 qualified 2 A synchronous buck regulator that converts 3.8 V to 36 V input to a fixed 5 V output at a nominal 2.1 MHz switching frequency.

Best for

  • Automotive 5 V rails
  • Infotainment and instrument clusters
  • Telematics control units
  • Compact 2 A buck conversion

Avoid if

  • An adjustable output voltage is required
  • A fixed switching frequency is mandatory at light load
  • Input voltage can exceed 36 V without external protection

Check before use

  • Confirm 5 V fixed-output suitability
  • Validate startup and load transient response with actual output capacitors
  • Verify junction temperature under worst-case ambient and load
