Voltage Regulators - DC DC Switching Regulators

3 A36 V input1.4 MHzAEC-Q100synchronous buckVQFN-HR

LMR33630BQRNXRQ1 is a 3 A automotive synchronous buck regulator for converting 3.8 V to 36 V inputs to an adjustable 1 V to 24 V output at a nominal 1.4 MHz.

Best for

  • Automotive 12 V-derived power rails
  • Compact 3 A point-of-load buck conversion
  • Applications needing adjustable output voltage

Avoid if

  • Input voltage can exceed the protected 36 V operating limit
  • A fixed switching frequency is required at all load currents
  • PCB area cannot support adequate thermal spreading

Check before use

  • Input surge and reverse-current conditions
  • Inductor saturation current versus current limits
  • Output capacitor effective capacitance and transient response
  • Thermal performance at maximum ambient temperature
