Non-isolated buck Module Rectification: We will use solar panels so that would do it. It’s a good habit to get into. The next question is can the LM handle more than 3A? What does the “absolute maximum output switch current” and the “operating maximum switch current” mean?
Welcome to Elecrow Online Store. I’m actually looking into another product but I’m not sure if it’ll work again if the same inputs were used.
LM2577-12.0 Boost Converter Overview
If so, I’d have no problems with it. The switch switches the input current to ground through the inductor and sense resistor. I only get 0.
Distributor Cooperated Designers Sponsorship. This is your maximum input current. Non-synchronous rectification Input voltage: 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 other 3W is wasted as heat. The output switch can’t handle it. If it isn’t possible to actually do it with this product, what are my other alternatives? Digikey might be a good place to start.
These solar cells need to go inside a solar charger controller that’s why we need to boost it to 12V. This module uses the adjustable output version, it would facilitate your application and be your good assistant in your debugging.

My Cart – 0 item. First, always get your datasheet straight from the manufacturer. Datasheeg Questions Tags Users Unanswered. Find a different, more modern part with synchronous rectification, and while you’re at it, reevaluate whether you really need to datasheett a 3V source. I bought 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.

I have a hard time fully understanding the datasheet of LM What you’re wanting is physically not possible. Granted, it’s a bit difficult to calculate ml2577s 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.
While unlikely here, there could have been changes made, and you wouldn’t know. Please sign llm2577s to the Market mailing list to receive updates on new arrivals, special offers and other discount information.
