LMR36006FSC3RNXRQ1 is a 60 V, 0.6 A automotive synchronous buck regulator with fixed 3.3 V output, 2.1 MHz forced-PWM switching, and spread-spectrum operation.

Best for

  • Automotive 3.3 V rails from wide DC input supplies
  • ADAS camera modules
  • Body control modules requiring fixed-frequency switching

Avoid if

  • Output current exceeds 0.6 A
  • Very low no-load current is required
  • The application cannot tolerate possible output-to-input reverse current in FPWM operation

Check before use

  • Verify junction temperature remains below 150 °C in the final layout
  • Use a 100 nF bootstrap capacitor between BOOT and SW
  • Use a 1 µF ceramic capacitor from VCC to ground
  • Confirm input capacitors and layout are suitable for the maximum input transient
