Most Helpful Customer Reviews

I bought several of these because they are far superior to using a normal LM317 linear regulator circuit, and they are less expensive in the end anyway. It would cost me more to buy the components to build a 3A linear regulator circuit (2x LM317, capacitors, resistors, potentiometer, protoboard and a heat sinks) than it cost me for one of these buck converters.

In addition to saving me money, these are so much more efficient and have a more consistent output voltage than a linear regulator. Linear regulators waste so much power just turning it into heat, which can be a real problem because they require bulky heat sinks and even still they can get hot enough to burn your fingers, melt plastic and just simply be a pain in the butt.

These buck converters don't heat up at all with a 600mA load, and barely get warm to the touch with a 1500mA load. You'll never have to worry about heat issues with these things. The output voltage is very stable, and DOES NOT DROP... Read more
I ordered this switching voltage regulator after classic 7805 turned out to heat too much due to too big a voltage drop (15V input). I needed higher input voltage to power the LCD. I wanted to use the same power brick for a constant 5V for Raspberry Pi. This product seemed perfect. Multi turn potentiometer allows me to set voltage precisely, down to a single mV. It powers Raspbery Pi and audio amplifier with ease. One unknown is long term voltage stability.
This order came straight from China, so it took two weeks to fulfill, but the price was good.
I will use another one in the next project. Those regulators are tiny, yet efficient, so they do not dissipate too much heat.
While they are incredibly efficient* and handy (I use them to power some 12V computer monitors off of a 24v battery bank) they have a few caveats.

First, don't let your voltage get low because rather than cutting off like you might hope they will simply keep trying to supply power at below the voltage level. This could damage some electronics, so use some sort of limiter (like a CJKIT-20462) to protect from low voltage if it matters for your application. (and the life of your battery!)

Second, they will audibly oscillate when drawing more than about 1A from a higher voltage source. You can hear the high pitched whine if you have sensitive ears. This annoying feature can be mitigated by lowering the input voltage.

* Third, and critical if you are operating on battery power: if your voltage source is substantially higher than the output voltage, this may burn a lot of amps even when the load draws little to nothing. My setup involves converting 25-28V... Read more
