Voltage Regulators - DC DC Switching Regulators

automotivesynchronous buck3.3 V fixed output2 A2.1 MHzVQFN

LMR33620CQ3RNXTQ1 is a 2 A automotive synchronous buck regulator with a 3.8 V to 36 V input range, fixed 3.3 V output, and 2.1 MHz switching frequency.

Best for

  • Automotive 3.3 V power rails
  • Infotainment and telematics power conversion
  • Compact synchronous buck designs

Avoid if

  • A variable output voltage is required without changing the device variant
  • The application cannot provide the recommended PCB area and thermal paths

Check before use

  • Input and output operating limits
  • Effective capacitance under DC bias and temperature
  • Inductor saturation and thermal margins
  • VQFN RNX land pattern and current-loop layout
