Voltage Regulators - DC DC Switching Regulators

buck converter3.3 V2 A2.1 MHzautomotiveVQFN

LMR33620CQ3RNXRQ1 is a fixed 3.3-V, 2-A synchronous buck regulator operating from 3.8 V to 36 V at a nominal 2.1 MHz switching frequency.

Best for

  • Automotive 3.3-V point-of-load conversion
  • Infotainment and telematics power rails
  • Compact high-frequency buck designs

Avoid if

  • An adjustable output voltage or output current above 2 A is required

Check before use

  • Input transients must remain within the absolute maximum ratings
  • The VQFN thermal and PCB layout requirements must be satisfied
  • Effective capacitor values under DC bias and temperature must meet the design requirements
