LM2577-12.0 Boost Converter Overview
Okay, that I understand. Digikey might be a good place to start.
While unlikely here, there could have been changes made, and you wouldn’t know. 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.
LM DC-DC Adjustable PSU Module
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 lm2577 the product. Email Required, but never shown.
If it isn’t possible to actually do it with this product, what are my other alternatives? The other 3W is wasted as heat. If you’re trying to get 15V at 3A, this part is not going to do it. Sign up 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.
Non-synchronous rectification Input voltage: Enter your destination to get a shipping estimate.
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 than output current. See Matt Young’s answer above. The LM series of regulators are monolithic integrated circuits that provide all the active functions for a step-up buck switching datashet, capable of driving a 3A load withexcellent line and load regulation.
Adjustable DC-DC Booster- LM2577
Post as a guest Name. It’s a good habit to get into. We will use solar panels so that would do it. I need to boost a 3V source to 15V and this is nicely done by the product. TI released a revised version in April What you’re wanting is physically not possible. These solar cells need to go inside a solar charger controller that’s why we need to boost it to 12V.

The dqtasheet switch can’t handle it. Henry Lachica 8 6. I’m trying to work around it. The switch switches the input current to ground through the inductor and sense resistor.
Find a different, more modern part with synchronous rectification, and while you’re at it, reevaluate whether you really need to use a 3V source. The next question is can the Datazheet handle more than 3A?
components – Question on LM – Electrical Engineering Stack Exchange
Please, log in or register. 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.
Lm2577d buck Module Rectification: The problem is the current out would not be enough when we use a boost converter. What does the “absolute maximum output switch current” and the “operating maximum switch current” mean?
This is your maximum input current.
