Review on 10PCS MP1584EN 3A Mini Step Down Buck Converter - 24V To 12V 9V 5V 3V Adjustable Module For Raspberry Pi Robort Parts DIY Kit by Joseph Hamilton
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.
- Work well.
- 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
