    A good DC-DC converter. I use it to regulate the output power of a LED power supply for my hobby projects. The filter capacitor for the trimmer potentiometer has a dedicated spot on the PCB. This is not common for some of these boards which can be annoying when you want to replace the trimmers to some other potmeters. The solders look nice and clean. Heatsink goes hot when larger power is used, so it is a good idea to use some fan to keep it cool.

    Good DC to DC changer. Useful for your DIY projets. Up to 300W just with the quick cooler othervise it can burn-out very quickly. Good design with the srew in conductors sockets. On-off switch is also advantage. Just dont exceed the input voltage it has no overvoltage input protection. The parametric data included which is great.

    Package is very well protected. I use it to step down 6S battery to charge other batteries with EMAX charger. I set output voltage to 18V and when charging, the alim output jump from 18V to 22-23 and back ! nothing but stable !! EMAX charger has a max input at 18V and it didn't warn for over voltage input so... finger crossed, look like ok

    very good, very easy to set up, using as current limiter for Banggood LED COB lights that were getting too hot

    It works fantastically, the trimmers are somewhat uncomfortable and the power switch is somewhat complicated to activate, but it has a very good efficiency and a good range of voltage and amperage reduction. tested with two lithium-ion batteries with 3.8v each, to use a 7.6v serial sum, reducing to stable 5v (Mark 4.8 because I need to calibrate that Voltmeter-Ammeter, tested with common multimeter).

    You will find this circuit as SZBK07. It is a very popular buck converter. There are several workarounds for this circuit which allows you to control it with some feedback loop. It is a great product for the price.
