If you want 15V 2. Question on LM Ask Question.

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. To see why, let’s take a look at the datasheet again. Finally, let’s do a sanity check with the data you provided.

Adjustable DC-DC Booster- LM2577

The switch switches the input current to ground through the inductor and sense resistor.

I have a hard time fully understanding the datasheet of LM The source is actually a solar panel.


Okay, that I understand. 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. Our price is lower than the manufacturer’s “minimum advertised price. Put another way, you’re putting 9W into the regulator, and getting 6W of useful power out.

Welcome to Elecrow Online Store. The output switch can’t handle it.

It’s just making life harder. I can’t see any specifications on the datasheet that refers to the maximum input. Granted, it’s a bit difficult to calculate exact switch datashet 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.

But the current isn’t the same because I need about 2.

See Matt Young’s answer above. HenryLachica The seller meant exactly what they said. If so, I’d have no problems with it. Non-synchronous rectification Input voltage: We would be able to supply 0. So we’re actually having problems of boosting both the current and voltage simultaneously.


You have no obligation to purchase the product once you know the price.

What I actually need: The output switch current has 6A listed as an absolute max, and 3A operating. You may also like. The maximum switch current is exactly that: Sign up using Email and Password. Distributor Cooperated Designers Sponsorship.

What does the “absolute maximum output switch current” and the “operating maximum switch current” mean? We will use solar panels so that would do it. What you’re wanting lm2577z physically not 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. Non-isolated buck Module Rectification: The next question is can the LM handle more than 3A? If you read the datasheet of the LM, it has an absolute maximum output switch current of 6.
