LMQ66430 evaluation module for 36-V, 3-A, Enhanced HotRod™ QFN, synchronous step-down converter


Order now


The LMQ66430-2EVM evaluation module (EVM) helps designers evaluate the operation and performance of the LMQ66430-Q1 device, a synchronous step-down DC/DC converter capable of driving up to 3 A of load current from an input voltage of up to 36 V. The LMQ66430-Q1 has ultra-low operating quiescent current, high efficiency at light loads and comes in a small 2.6-mm × 2.6-mm Enhanced HotRod™ QFN package, which provides a low-EMI solution size.

  • Wide input voltage range of 3 V to 36 V
  • 3.3-V fixed output voltage by default
  • Output current up to 3 A
  • 2.2-MHz default switching frequency (jumper included for AUTO mode or FPWM selection)
  • Fully assembled, tested and proven printed circuit board layout with small-solution footprint
