SMAKN® DC 4.5-60V to 1.25-30V Lm2596hv Power Supply Buck Voltage Switching Regulator Module Step Down

I build prototypes, and often have several DC voltages inside one package. These allow me to easily use a single supply and split the output to as many of these as I need, with easily tunable voltage. So far, I have not run into any noise or other regulation issues—but have not needed them in any circuits that would be highly sensitive to DC noise.This has made my job easier, and brought mu costs down.

Good quality. Works well as a USB charger on my e- bike with a 48 volt battery. About the same size as the original DC to DC converter that I destroyed. Great replacement. fast shipping.The only negative was Amazon. Somehow, they thought I wanted to return the item, deducted the payment from the seller, then added back the charge when I didn't return it. Amazon is strange sometimes.

Nice circuit it works well. The SW connection must be connected to GND to function the board does not come with instructions for this. This is the only reason for 4 stars.

Used to run a 12v water pump off my 44v trolling motor battery. Works phenomenally.Almost all the available buck converters cut off at a rating of 36v. This is the only one that was rated up to 60v. Saved my project.

Works very well. It seems to be the only such item on Amazon that can be powered by 60v.

Solid so far for hoverboard hack dc dc step down from 42v to 5v

I have it set to step down from 36v to 12v. It works well for about 15 minutes, than it overheats and shuts off sporadically. My build project took longer than expected and I am passed the return window.

Does not have designated area to mount heat sink.
