components – Question on LM – Electrical Engineering Stack Exchange
If you’re trying to get 15V at 3A, this part is not going to do it. Power is conserved, and you lose a bit or more than a bit of power to the regulator i. 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.
I tried scanning through the datasheet and I fail to see its maximum input current. Sign up or log in Sign up using Google.
LM2577 DC-DC Step Up Adjustable PSU Module
There are may boost converters available. I have a hard time fully understanding the datasheet of LM I’m trying to work around it. We will use solar panels so that would do it. See Matt Young’s answer above. I’m actually looking into another product but I’m not sure if it’ll work again if the same inputs were used. Crowtail- Base Shield datasyeet Pyboard.
It’s not going to work. TI released a revised version in April My Cart – 0 item. The other 3W is wasted as heat.
We would be able to supply 0. This module uses the adjustable output version, it would facilitate your application and be your good assistant in your debugging. While unlikely here, there could have been changes made, and you wouldn’t know.
Adjustable DC-DC Booster- LM2577
Because it is a boost converter and you can’t break physics. Put another way, you’re putting 9W into the regulator, and getting 6W of useful power out. So we’re actually having problems of boosting both the current and voltage simultaneously.
Please, log in or register. The maximum switch current is exactly that: If you want 15V 2. Enter your destination to get a shipping estimate. Home Questions Tags Users Unanswered. 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. These solar cells need to go inside a solar charger controller that’s why we need to boost it to 12V.
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. Several datashwet to look at here It’s a good habit to get into.
This is how a basic boost regulator works. But the current isn’t the same because I need about 2.

What does the “absolute maximum output switch current” and the “operating maximum switch current” mean? Non-synchronous rectification Input voltage: This is your maximum input current. If so, I’d have no problems with it. Post as a guest Name. I only get 0. To see why, let’s take a look at the datasheet dwtasheet.
