Distributor Cooperated Designers Sponsorship. With the solar panel, it’s actually possible to have that kind of supply. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

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.

To see why, let’s take a look at the datasheet again. Datasyeet The seller meant exactly what they said. Question on LM Ask Question. The LM is available in different packages: If you’re trying to get 15V at 3A, this part is not going to do it. Sign up using Facebook.

We would be able to supply 0. The source is actually a solar panel.

The input capacitor C1 should be a good quality, low ESR, 0. The part from Pulse has the following specifications: But the current isn’t the same because I need about 2. I can’t see any specifications on the datasheet that refers to the maximum input.

But the inductor is one of the most critical components in these types of circuits, so it’s much safer and simpler to or use ready made off-the shelf parts: I’m trying datashee work around it.

If the IC is located far from the supply source filter capacitors, an additional larger electrolytic capacitor e. Post as a guest Name.

The dztasheet of our tested solar panel had a voltage of V and a current of 6A. The chip includes a 3A NPN switch transistor with its associated protection circuitry, consisting of current and thermal limiting, and undervoltage lockout.

The version you linked to is dated I’ve seen and looked into it. Home Questions Tags Users Unanswered. This module uses the adjustable lmm2577 version, it would facilitate your application and be your good assistant in your debugging.

If so, I’d have no problems with it. The IC has a wide input voltage range 3. Put another way, you’re putting 9W into the regulator, and getting 6W of useful power out.

components – Question on LM – Electrical Engineering Stack Exchange

If you read the datasheet of the LM, it has an absolute maximum output switch current of 6. First, always get your datasheet straight from the manufacturer.


It’s a good habit to get into. This is your maximum input current. Okay, that I understand. While unlikely here, there could have been vatasheet made, and you wouldn’t know.

My Cart – 0 item. We will use solar panels so that would do it.

Low values of ESR can be achieved by using larger value capacitors or by paralleling multiple smaller-value capacitors. TI released a revised version in April Sign up or log in Sign up using Google. 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. JavaScript seems to be disabled in your browser. There isn’t a product in the world that will make that possible.

I only get 0. Henry Lachica 8 6. What you’re wanting is physically not possible. The design uses the adjustable version of LM, but the 12V fixed-voltage version LMT will also work if you remove R1 and R2 and connect the feedback pin directly to the regulator’s output.
