    These are nice tiny regulator boards that will fit almost anywhere. I tried one on a LED lamp and it runs cool and efficient. One note is the adjustment trim-pot adjusts backwards, turn it clockwise to lower the voltage. Out of the box they were set full counter-clockwise for maximum voltage output, so measure before connecting to the load.

    Inexpensive dc switching regulator.

    For the low cost, you can't go wrong. But, beware: the output has a sinusoidal ripple that can create interference problems. The ripple was adequately suppressed by adding a 1000uf capacitor on the output. It seems to be a stable regulated dc output when capacitor is added.

  • Top critical review

    Very noisy supply. Cannot sustain more than 1.5A. 30mA idle draw. Otherwise fine

    I am going to share my experience of testing and using this device. My intended application was putting it in my car for bluetooth audio purposes. This meant taking a 13.8v input and converting it down to 5v. First, a comment on size and quality. The converter is about the size of a quarter. All solder joints looked fine to me. I didn't notice any cracking or oxidation in the joints. The potentiometer is a bit small, but can be manageable with a VERY small screw driver. Now on to my testing. I used a very high quality HP benchtop supply, a Fluke voltmeter, an IR temperature meter, some 2-10ohm 100W resistors, and a DSO 138 oscilloscope. Using these I tested the converter at various loads to determine voltage ripple and temperature. Looking at the first photo, we can see there is ...

  • Small and adequate in many cases.

    It does reasonably well considering the size. Getting the output to desired voltage is tricky. There is a another board (MP1584) but for my app the MP2307 is fine. I did not try putting it under much load, just powering a teensy board.

  • Great little buck power supplies for a great price

    The only bad thing I can say about these is they are very small. If you have not seen a picture of one of these to scale they will sit on a US quarter. This is not bad, but something to be aware of. The input and output are clearly marked and are easy to solder to. The little one turn trimpot was surprisingly easy to set to within a few millivolts of where I wanted it. I plan on using these as = 5V to 3.3V regulators and I had thought about replacing the trimpot with fixed resistors (I am surprised they don't come fixed in a few popular voltages..) but because of the physical size I don't think my soldering skills are up to the task. Though at the price I may give it a shot on one. I do think I can do it but I don't think it would be pretty. Anyway, these take about a 1.5V ...

  • Great little adjustable voltage drops

    I buy these often as they work so well. I use them in my model railroad, using them with a bridge rectifier in train cars running on DCC to control circuit with clean voltage. You cant build something this good from scratch.. With LEDs today these are a must. recently I bought several 53' refrigerator containers that required 9v battery's, well with this and metal wheels I run them all on track power..
