LMS3655MQRNLRQ1

Voltage Regulators - DC DC Switching Regulators

automotivesynchronous buck5.5 Aadjustable output400 kHzVQFN-HR

LMS3655MQRNLRQ1 is an automotive synchronous buck regulator rated for up to 5.5 A, with adjustable output and a 400-kHz nominal switching frequency.

Best for

  • Automotive power rails
  • High-current DC-DC step-down conversion
  • Adjustable-output designs requiring spread-spectrum operation

Avoid if

  • The design needs an output voltage above the documented extended range
  • The PCB cannot provide the required thermal and high-current layout

Check before use

  • Input voltage and transient conditions
  • Output voltage, load current, and dropout margin
  • Inductor saturation current and capacitor effective capacitance
  • Thermal rise and RESET/FPWM/SYNC pin configuration
