Excellent converter. Very low idle draw. Very minimal voltage ripple
I am going to share my experience of testing and using this device. My 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. 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 is the hottest temperature observed at about 500mA load. No complaints here. The next photo is the voltage ripple ... I am going to share my experience of testing and using this device. My application was putting it in my car for bluetooth audio purposes.

Using these I tested the converter at various loads to determine voltage ripple and temperature. Looking at the first photo is the hottest temperature observed at about 500mA load. No complaints here. The next photo is the voltage ripple observed at about 1500mA load. With a VPP of 3mv and no observable frequency, I'd say this is a very clean converter. At this load, the third photo shows a temperature of 87F. Very acceptable. Some people on another site had concerns about using these at very low loads, but I didn't notice anything when going down to about 200mA loads. Now I start to test the limits of the device. At a 2A load (seen in photo 4), I was able to sustain this load without too much of an increase in temperature (around 100F). About average I would say. But the important bit here is that I was able to sustain this load for an indefinite amount of time. Moving on to the last photo, I tested the device at about a 2.5A load. Temperatures rocketed up to about 154F and (after about 2 minutes) the device would turn on and off. So for anything under 2A, this device will work great for you. Not shown here is the idle current, but it didn't even show up on my benchtop supply (so less than 10mA). Overall, very impressed with this device. It is accurate to it's description and I will definitely be using some more in the future.

Good value, but applications may be limited
I should've checked the driver datasheet and compare with the item photo. The item uses a 4.7uH inductor, which is too low unless you use this for 1.8V output according to the datasheet. This can be played with by other parameters, such as switching frequency and a compensation circuit though. I started with 12V input and 5V output with a DMM, and thought it seems doing what it's supposed to do. Then, I tried 12V input and 3.3V output. At a lighter load, no problem, but with a heavier load >1A, I noticed higher voltage than what it's set to. So, I pulled my o-scope. 0.1A load, no problem, seems reasonably quiet (< 20mV p-p). But at 1A load, it's basically ringing/oscillating, >800mV p-p. I tried a few different 12V power supplies, but nothing helped there. I looked into the item, and was ...

But at 1A load, it's basically ringing/oscillating, >800mV p-p. I tried a few different 12V power supplies, but nothing helped there. I looked into the item, and was thinking about changing the switching frequency or compensation circuit, but I don't have any SMD resistors or caps with me now, unfortunately. I added input caps, but didn't help. Finally, I saw a significant change when adding a 22uF AL-EL cap. (Please note that even though I said I didn't see any issues with 12V input and 5V output, I didn't take a close look with an o-scope, so the similar issue may occur at different voltage setup, as well) Lastly, I used the item with 5V input. It works with some load, but when no load, it again oscillates >1.5V p-p. I haven't looked up the driver's minimum head-room for input over output, but without load, it shouldn't behave like this. In summary, do I recommend this item? No, unless you know what you are doing and what you are using it for. Good value, yes. Good quality? Assembly seems clean, but I'd have to say it's a questionable design. What if I design this? I would limit the application voltage range, or increase the board size so it can work better for wider voltage. Just my two cents.
