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. Feedback If you are a seller for this product, would you like to suggest updates through seller support?

What you’re wanting is physically not possible. The source is actually a solar panel. There was a problem filtering reviews lm2757 now. You may also like. Finally, let’s do a sanity check with the data you provided.

The voltage adjustment is very touchy.

To see why, let’s take a look at the datasheet again. Page 1 of 1 Start over Page 1 of 1. Amazon Renewed Refurbished products with a warranty. Even if the switch was l2577 to it, the 3V source would have to supply over 20A.

Product information Package Dimensions 3 x 2 x 0. HenryLachica The seller meant exactly what they said.

This module uses the adjustable output lm25577, it would facilitate your application and be your good assistant in your debugging. The output voltage is given by the following formula:. I can’t see lmm2577 specifications on the datasheet that refers to the maximum input. Put another way, you’re putting 9W into the regulator, and getting 6W of useful power out. Non-synchronous rectification Input voltage: 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 lm25777 current of 3A.

Because it is a boost converter and you can’t break physics. Low values of ESR can be achieved by using larger value capacitors or by paralleling multiple smaller-value capacitors. Welcome to Elecrow Online Store. The next question is can the LM handle more than 3A? However I have constructed this circuit and with an input voltage of 3.
