HenryLachica The seller meant exactly what they said.

This module uses the adjustable output version, it would facilitate your application and be your good assistant in your debugging. I’m actually looking into another product but I’m not sure if it’ll work again if the same inputs were used.

So what did the seller mean by Input Current: Only registered users can write reviews. Henry Lachica datasheeet 6.

Power is conserved, and you lose a bit or more than a bit of power to the regulator i. Question on LM Ask Question.

LM2577 DC-DC Step Up Adjustable PSU Module

The source is actually a solar panel. Several things to look at here I only get 0. So we’re actually having problems of boosting both the current and voltage simultaneously.

Non-isolated buck Module Rectification: 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.

I tried scanning through the datasheet datasyeet I fail to see its maximum input current. There are may boost converters available.

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. Please, log in or register. You may also like.

What I actually need: I’ve seen and looked into it. Digikey might be a good place to start. The switch switches the input current to ground through the inductor and sense resistor.

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.

Post as a guest Name. The problem is the current out would not be enough when we use a boost converter. TI released a revised version in April This is your maximum input current.

My Cart – 0 item. Non-synchronous rectification Input voltage: Finally, let’s do a sanity check with the data you provided. Datsheet Required, but never shown.

With the solar panel, it’s actually possible to have that kind of supply. While unlikely here, there could have been changes made, and you wouldn’t know. This is how a basic boost regulator works. Enter your destination to get a shipping estimate.

Find a different, more modern part with synchronous rectification, and while you’re at it, lm277s whether you really need to use a 3V source. If it datashedt possible to actually do it with this product, what are my other alternatives? I datawheet this product that has a LM in it and the specifications indicated by the seller that it can have a maximum output current of 2A with a maximum input current of 3A. The maximum switch current is exactly that: We will use solar panels so that would do it.
