Garbage, incorrect specs

Mar 07, 2021

Either this product has changed or the specs are grossly misleading. It is very unfortunate that the photos don't show the other side of the board, it would have been obvious what this is.
The module uses an XL2576s DC-DC converter, which is nothing else but a clone of the good old LM2576xx "Simple Switcher" series from Texas Instruments.
That converter's datasheet specifies *3A max* output current capability, the 5A is the absolute maximum current through the internal switch (so including any ripple currents through the inductor). So the "Max 5A" on the label is complete nonsense, you will never be able to reach (or even get anywhere near) that.
However, even at 3A it is unusable - the IC gets very hot and the thermal protection will kick in quickly because the only "heatsink" is the PCB itself. The Simple Switcher series is a very old design that is not very efficient so heatsinking is a must - but essentially none is provided, so no chance to push this module anywhere near its specs.
Worse, the output voltage drops to about 4.3V when set to 5V output and trying to draw 3A using an electronic load. Oh and the output ripple is over 1V peak-to-peak in that situation too!
I guess the fact that the datasheet does not specify any value for the output ripple except stating that it has a "low ripple" and the bundled large green ferite toroid should have been a dead giveaway that this is not going to be a low noise solution.
This module is somewhat usable up to 1A of current but then there are much better solutions available. E.g. this: https://hobbyking.com/en_us/kingkong-5v-3a-ubec.html
That KingKong BEC will not reach 3A neither but it will handle 1-1.5A with no fuss, with much lower ripple because it uses a much more modern converter IC running at higher frequency - and is about half the size and price than this Turnigy junk.
If I wanted a crappy LM2576 module, I could have bought it from eBay from 1/5th of the price. So much for relying on a brand name.

Power for my gliders with a Lipo

Jan 05, 2021

I'm using this SBEC as power supply for gliders. A 2s Lipo is the source and this SBEC vonverts it to 5V.
Perfect
