    Finally i received my buck-converters, expect those to be as stable as the first I ordered. (identical PCB's :-) ;-) ) Function perfect as switch-down PSU for LED-strips where I distribute from a 22-26V unstabilized (transformer/rectifier) or a 24V DC PSU. Only negative about this Buck-converter is the trimmer which I replace with an 0805 resistor with a value needed for the given LED-strip voltage-need. Runs easily up to 0.75A without cooling and above that just a small cooling-fin clued on the back-side.

    zuverlässige Spannungsregler für variabel einstellbare Spannungsversorgung Input voltage: 4.5V ~ 28V Output voltage: 0.8V ~ 20V Output current: rated current is 2A

    We use this step-down converter to supply 5 V DC for 5 V LEDs stripes.

    Great power supply, 200uA quiescent current is real, 2A long term, 3A short term due to warming . . .

    Very useful dc dc hard to make so small pcb by yourself(also cheaper), using it to charge lithium batteries inside closed case projects..., just make sure you don't discharge it too much , just set it to 4.15-4.18v (cv) (better don't set it to 4.2v) and it will slowly stop charging when it reach when voltage of the battery rises to 4.xx(the one you set), better don't use it to charge in series, just single or parallel

    I bought 20 units of them and I already put some into "production". As the specification said, the user will need additional heatsink to avoid overheating and self-shutdown. Several times I made mistake and put 20V into the input in inverted polarity, but the converter survived without and issue. Also, if the current is too much and the chip overheated (it can be pretty hot! under high load: >1500mA) the chip stops working (turned off itself) but as it will be cooler, it will switch on again. So,
