A Step-Down Switching Regulator Using MP1584


Updated 27/08/2021

SKU: MODULE-003 Categories: , Tags: , , ,


The MP1584 is a high frequency step-down switching regulator with an integrated internal high-side high voltage power MOSFET. It provides 3A output with current mode control for fast loop response and easy compensation.

The wide 4.5V to 28V input range accommodates a variety of step-down applications, including those in an automotive input environment. A 100µA operational quiescent current allows use in battery-powered applications.

Product includes professional library, confirmed schematic design. Our design has also a full output job and active Bill of Materials.


  • Wide 4.5V to 28V Operating Input Range
  • Fixed 3.3V @ 3A Output (Change output voltage by feedback resistor network)
  • Programmable Switching Frequency from 100kHz to 1.5MHz
  • Internal Soft-Start
  • Ready to use in your devices
  • Small size 25x15.5mm
