Because it is a boost converter and you can’t break physics. 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.

Okay, that I understand. Put another way, you’re putting 9W into the regulator, and getting 6W of useful power out. This module uses the adjustable output version, it would facilitate your application and be your good assistant in your debugging.

I have a hard time fully understanding the datasheet of LM What you’re wanting is physically not possible.

This is how a basic boost regulator works. Non-isolated buck Module Rectification: Find a different, more modern part with synchronous rectification, and while you’re at it, reevaluate whether you really need to use a 3V datashete. It’s not going to work.

Distributor Cooperated Designers Sponsorship. So if we stack it up, we’re gonna have a total of 4V datasjeet 6A, as a source tested the solar cells during a very hot day. The output switch current has 6A listed as an absolute max, and 3A operating. You can simply remove the item from your cart. If you want 15V 2. It’s a good habit to get into.

I’m actually looking into another product but I’m not sure if it’ll work again if the same inputs were used. Email Required, but never shown. I only get 0. The next question is can the LM handle more than 3A?

If it isn’t possible to actually do it with this product, what are my other alternatives? To see why, let’s take a look at the datasheet again.

I’ve seen and looked into it. So what did the seller mean by Input Current: The source is actually a solar panel. I’m trying to work around it. But the current isn’t the same because I need about 2. HenryLachica The seller meant exactly what they said. 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. Welcome to Elecrow Online Store. Several things to look at here If so, I’d have no problems with it.

Question on LM Ask Question. Granted, it’s l2577s bit difficult to calculate exact switch current from a desired output current, but the point is, at a max switch current of 3A, it’s definitely not going to give you 13A switch current is always higher than output current. I need to boost a 3V source to 15V and this is nicely done by the product.

Non-synchronous rectification Input voltage: We would be able to supply 0. You must have JavaScript enabled in your browser to utilize the functionality of this website.

I can’t see any specifications on the datasheet that refers to ln2577s maximum input. We will use solar panels so that would do it.

LM2577-12.0 Boost Converter Overview

See Matt Young’s answer above. The problem is the current out would not be enough when we use a boost converter.
