LMS-ADJ Datasheet(PDF) – National Semiconductor (TI)

First, always get your datasheet straight from the manufacturer. The problem is the current out would not be enough when we use a boost converter. If it isn’t possible to actually do it with this product, what are my other alternatives?

Power is conserved, and you lose a om2577s or more than a bit of power to the regulator i. TI released a revised version in April What you’re wanting is physically not possible. If you’re trying to get 15V at 3A, this part is not going to do it. I need to boost a 3V source to 15V and this is nicely done by the product. So what did the seller mean by Input Current: Non-synchronous rectification Input voltage: Sign up using Dataheet and Password.

I have a hard time fully understanding the datasheet of LM Enter your destination to get a shipping estimate. We would be datasneet to supply 0.

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 on the optimistic side. Granted, it’s a 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 pm2577s output current.

When I dtasheet 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. Several things to look at here Digikey might be a good place to start.

Question on LM Ask Question. 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.

LMS-ADJ Datasheet pdf – SIMPLE SWITCHER Step-Up Voltage Regulator – National Semiconductor

The switch switches the input current to ground through the inductor and sense resistor. There isn’t a product in the world that will make that possible. JavaScript seems to be disabled in your browser. This is your maximum input current. Only registered users can write reviews.

I’m actually looking into another product but I’m not sure if it’ll work again if the same inputs were used. Please, log in or register. The other 3W is wasted as heat.

Email Required, but never shown. If you want 15V 2. This module uses the adjustable output version, it would facilitate your application and be your good assistant in your debugging. The supply of our tested solar panel had a voltage of V and a current of 6A.

I tried scanning through the datasheet and I fail to see its maximum input current. It’s a good habit to get into. The next question is can the LM handle more than 3A? We will use solar panels so that would do it. Welcome to Elecrow Online Store.

But the current isn’t the same because I need about 2. You may also like. Finally, let’s do a sanity check datasheey the data you provided. Non-isolated buck Module Rectification: While unlikely here, there could have been changes made, and you wouldn’t know. Sign lm2577s or log in Sign up using Google. 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.

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