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.Verified purchase: YesCondition: New

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.Verified purchase: YesCondition: New

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 differential before they kick on. For my 3.3V output they came on at around 4.7 to 4.8V on the input and maintained 3.3V on the output with up to 16V or so on the input (the limit of my bench supply). I did not do any efficiency tests, but from what I saw in the data sheets and on the internet, these should be 90%+ efficient with around 5V in and 3.3V out. I am happy with my purchase. You can not get a name brand fixed linear regulator for what one of these will set you back. I can see these being real popular in solar powered applications. One to step the cells up to charge the battery pack and one to take the battery down to match the 8266..Verified purchase: YesCondition: New

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 already a 30mA idle current. I believe this item is intended in small applications (likely running on battery power), so definitely keep this in mind. Compared to the other converter, this is way higher. Time to test this under load. The second and third photos show very high voltage ripple observed at about a 500mA load. Both values obtaining 40mv VPP at frequencies of 1.1kHz and 10kHz. Both would be easily heard anywhere in your audio equipment (unless you put some capacitors in there for filtering). For audio purposes I would not use this item. Moving on to the last two photos. The fourth photo is the average temperature observed at the hottest point on the board running at around 1A load. At 1.5A load, the final picture shows temperatures observed. At this point, the converter could hold this load for about 30 seconds before it started turning on and off. Not sure where they get their claim for 1.5A sustained power and 3A peak. I tried multiple devices to make sure I didn't have a dud, but they all reproduced the same results. Overall, I'm not really impressed with this converter. I'd strongly recommend grabbing their other MP1584 device, as it's much more reliable, cleaner voltage signal, and very similar in size. I would only use this if I needed a power source which did not care about noise levels. I likely won't be getting any of these in the future.

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..Verified purchase: YesCondition: New

Ardunio project saver, makes voltage challenge easy to solve!
Buck Converter Micro Sized Very Convenient Presoldered connect points, easy to use and fit into many concealed locations. Rating may be exaggerated, i got just up to 2 Amps before it got too hot and started dropping out/ self shutdown (heat?). Ripple on output is easily filtered with additional capacitor (i used small 10mfd / 20v rated) These only do a down convert to a lower voltage than the input.Verified purchase: YesCondition: New

Trash
These things are trash. Be warned! The adjustment screw is so small even with the tiniest of precision screwdrivers it is nearly impossible to turn. THEN once you do get it to turn, it doesn't change anything. Output remains exactly the same (not even a full volt below i put voltage @ 12v). Buy different ones!Verified purchase: YesCondition: New

Outstanding!
I replaced a L7805 in my robot with this module and was amazed at the difference. The L7805 was running far less current than it is rated for (running 200ma rated for 1000ma) and it was running far TOO hot to use without a heatsink, this module wired into the same circuit runs cool as a cucumber!!! Also with the adjustable output I can get the 6v that I need for the motors.Verified purchase: YesCondition: New

Nice little unit.
I like that they are small ( and light weight ). Kind of fragile, but that's expected. I like the input/output voltage ranges and it is nice to be able to dial in the correct voltage, but is a bit hard to get it exactly where you want it with the screw resolution. They are small and a bit finicky to work with, but not crowded at the terminals. Overall, very pleased.Verified purchase: YesCondition: New

Great value and small form factor.
A great form factor with delicate voltages setting. Be careful with adjustments. This is a wonderful value.Verified purchase: YesCondition: New
