Description of 10PCS MP1584EN 3A Mini Step Down Buck Converter - 24V To 12V 9V 5V 3V Adjustable Module For Raspberry Pi Robort Parts DIY Kit

Mini MP1584EN DC-DC buck adjustable step down module. Input voltage: 4.5V to 28V; Output voltage: 0.8V to 20V adjustable, Output current: 3A (maximum), less than 2.5A, Conversion Efficiency: 92% Max, Output ripple: Less than 30mV, Switching Frequency: 1.5MHz Max, 1MHz TYP. 1.0MHz Switching Frequency, <30mV ripple (no load), MP1584 IC. Smaller size just like the size of a coin, but it's only 2g, much lighter than the coin. So it's really a perfect solution for projects that have strict requirements on product volume and weight, such as aviation model. Wide Range of Applications: DIY mobile power supply, monitoring power supply, camera power supply, vehicle power supply, communication equipment power supply etc.

Perfect. Good design. Better than the other popular buck design.

Yes. They are small but with a magnifier and good solder skills, you can breeze through the setup. Be sure to cut the adjustable line as directed to remove the potentiometer when using fixed values. (e.g. 5v)

Pros
  • 1.0MHz Switching Frequency, &lt;30mV ripple (no load), MP1584 IC.
Cons
  • Difficult to install

Do not output selected voltage

I tried 4 of them at 3.3, 5 and 9 volts output with 12 volts input. In all cases the output voltage was much too low to operate the micro controllers. Even though the adj pads were not shorted the potentiometer would change the output. If the adjustable pads are shorted the I still could not get 5 volts output. On the plus side they are small and inexpensive.

Pros
  • Work well.
Cons
  • Despite being marketed as adjustable, users have found that these converters sometimes fail to deliver the expected output voltage or experience significant fluctuations in voltage regulation
