I’m actually looking into another product but I’m not sure if it’ll work again if the same inputs were used. 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.

Sign up using Email and Password. 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. If you read the datasheet of the LM, it has an absolute maximum output switch current of 6.

You may also like. There are may boost converters available.

There isn’t a product in the world that will make that possible. So if we stack it up, we’re gonna have a total of 4V and 6A, as a source tested the solar cells during a very hot day.


There is a very good chance that ” is a Chinese counterfeit so the chip specs may be different from the TI part, and the board specs are probably datashest the optimistic side. Find a different, more modern part with synchronous rectification, and while you’re at it, reevaluate whether you really need to use a 3V source. If it isn’t possible to actually do it lm22577s this product, what are my other alternatives? So what did the seller mean by Input Current: What I actually need: The maximum switch current is exactly that: Power is conserved, and you lose a bit or more than a bit of power to the regulator i.

This is your maximum input current. HenryLachica The seller meant exactly what they said.

It’s a good habit to get into. Email Required, but never shown.

LM2577 DC-DC Step Up Adjustable PSU Module

The other 3W is wasted as heat. This is how a basic boost regulator works. We would be able to supply 0. With the solar panel, it’s actually possible to have that kind of supply. Home Questions Tags Users Unanswered. Okay, that I understand. Question on LM Ask Question. So we’re actually having problems of boosting both the current and voltage daatasheet.

I’ve seen and looked into it. Several things to look at here Enter your destination to get a shipping estimate. My Cart – 0 item. You have no obligation to purchase the product once you know the price. Crowtail- Base Shield for Pyboard.

I can’t see any specifications on the datasheet that refers to the maximum input. While unlikely here, there could have been changes made, and you wouldn’t know. I only get 0. If you’re trying to get 15V at 3A, this part is not going to do it. But the current isn’t the same because I need about datasjeet.

Henry Lachica 8 6. The supply of our tested solar panel had a voltage of V and a current of 6A.

First, always get your datasheet straight from the manufacturer. Post as a guest Name. I need to boost a 3V source to 15V and this is nicely done by the product. Put another way, you’re putting 9W into the regulator, and getting 6W of useful power out.
