LM DC-DC Adjustable PSU Module

I’m trying to work around it. HenryLachica The seller meant exactly what they said. It’s a good habit to get into. The supply of our tested solar panel had a voltage of V and a current of 6A. Post as a guest Name. The source is actually a solar panel. I bought this product that has a LM in it and the specifications indicated by the seller dafasheet it can have a maximum output current of 2A with a maximum input current of 3A.

I’ve seen and looked into it. That is pretty abysmal efficiency for a modern SMPS, but not outside of reasonable for the LM25xx era, and as much of a boost as you’re trying to get.


Finally, let’s do a sanity check with the data you provided. If you want 15V 2.

Power is conserved, and you lose a bit or more than a bit of power to the regulator i. I have a hard datasheeet fully understanding the datasheet of LM When I tried testing it, it seems that it can handle more current than 3A and i’m just too scared to test it out as I might break the product.

The maximum switch current is exactly that: Please, log in or register. Please sign up to the Market mailing list to receive updates on new datasyeet, special offers and other discount information.
