The LM series of regulators are monolithic integrated circuits that provide all the active functions for a step-up buck switching regulator, capable of dataasheet a 3A load withexcellent line and load regulation. The version you linked to is dated Only registered users can write reviews. The output dxtasheet is given by the following formula:. These solar cells need to go inside a solar charger controller that’s why we need to boost it to 12V.

Adjustable DC-DC Booster- LM2577

The output switch current has 6A listed as an absolute max, and 3A operating. When I tried testing it, it datassheet 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 UC – a pin to pin compatible replacement available from Texas Instruments can also be used.


What I actually need: I’ve seen and looked into it. What does the “absolute maximum output switch current” and the “operating maximum switch current” mean? TI released a revised version in April Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

Several things to look at here The LM is available in different packages: I’m trying to work around it. Distributor Cooperated Designers Sponsorship.

This is how a basic boost regulator works. Low values of ESR can be achieved by using larger value capacitors or by paralleling multiple smaller-value capacitors. You must have JavaScript enabled in your browser to utilize the functionality of this website.

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. The part from Pulse has the following specifications: Power is conserved, and you lose a bit or more than a bit of power to the regulator i.


Digikey might be a good place to start. You may also like. See Matt Young’s answer above.

Datashret so, I’d have no problems with it. Please sign up to the Market mailing list to receive updates on new arrivals, special offers and other discount information Subscribe.

If you’re trying to get 15V at 3A, this part is not going to do it. The LM integrated circuit datqsheet National Semiconductor is a useful IC that provides all of the power and control functions for a simple boost step-upflybackand forward converter switching regulator.

The IC has a wide input voltage range 3. The problem is the current datasheer would not be enough when we use a boost converter.

The other 3W is wasted as heat. Our price is lower than the manufacturer’s “minimum advertised price. I can’t see any specifications on the datasheet that refers to the maximum input.
