LM Datasheet pdf – Series SIMPLE SWITCHER Step-Up Voltage Regulator – National Semiconductor

The next question is can the LM handle more than 3A? See Matt Young’s answer above.

Finally, let’s do a sanity check with the data you provided. Email Required, but never shown. Datashest would be able to supply 0. Please sign up to the Market mailing list to receive updates on new arrivals, special offers and other discount information. This is your maximum input current. This is how a basic boost regulator works.


The LM integrated circuit from National Semiconductor is a useful IC that provides all of the power and control functions for a simple boost step-upflybackdatahseet forward converter switching regulator. Please, log in or register.

The source is actually a solar panel. Even if the switch was up to it, the 3V source would have to supply over 20A. You must have JavaScript enabled in your browser to utilize the functionality of this website.

The output voltage is given by the following formula:. Sign up using Facebook.

The LM series of regulators are monolithic integrated circuits that provide all the active functions for a step-up buck switching regulator, capable of driving a 3A load withexcellent line and load regulation. Enter your destination to get a shipping estimate.

I’ve seen and looked into it. To see why, let’s take a look at the datasheet again. There isn’t a product in the world that will make that possible. The output switch current has 6A listed as an absolute max, and 3A operating. This module uses the adjustable output version, it would facilitate your application and be dqtasheet good assistant in your debugging.

What I actually need: My Cart – 0 item. TI released a revised version in April Low values of ESR can be achieved by using larger value capacitors or by paralleling multiple smaller-value capacitors.


It’s a good habit to get into. What you’re wanting is physically not possible.

When I tried testing it, it seems that it datasehet handle more current than 3A and i’m just too scared to test it out as I might break the product. Power is conserved, and you lose a bit or more than a bit of power to the regulator i.

The UC – a pin to pin compatible replacement available from Texas Instruments can also be used. So if we stack ,m2577 up, we’re gonna have a total of 4V and 6A, as a source tested the solar cells during a very hot day. That is pretty abysmal efficiency for a modern SMPS, but not outside of reasonable for the LM25xx era, and as much of a datashet as you’re trying to get. If you want 15V 2.
