36 V buck regulator1 A output3.3 V fixed output2.2 MHzAEC-Q100 Grade 1VQFN-FCRLF

LMQ66410MC3RXBRQ1 is a compact automotive 1 A synchronous buck regulator with a fixed 3.3 V output and 2.2 MHz switching frequency.

Best for

  • Compact automotive 3.3 V rails up to 1 A
  • ADAS, infotainment, body electronics, and lighting power rails

Avoid if

  • An output voltage other than 3.3 V is required without using the adjustable feedback configuration
  • The application needs more than 1 A continuous output current

Check before use

  • Confirm worst-case junction temperature remains within -40 °C to 150 °C
  • Use the required 1 µF VCC capacitor and adequate effective input/output capacitance
  • Verify EMI and layout performance in the final PCB
