This is a DC-DC boost converter LM module based on TI LM Step-up Voltage Regulator. Input voltage: 3VV, Output voltage: V. LM DC-DC Adjustable Step-up Power Converter Module. The LM series of regulators are monolithic integrated circuits that provide al. LM DC to DC step up switching regulator, adjustable + to 30vdc output, up to 3A. The LM is really designed to step up +5 to 10vdc to +12vdc at.

We would be able to supply 0. Non-isolated buck Module Rectification: Based on other reviews of this product, I’m not willing to risk testing the device’s output any further than that, as sudden jumps of lm25577 or more and unexpected explosions are apparently not uncommon. It’s not going to work. Sign up using Email and Password. Please sign up to the Market mailing list to receive updates on new arrivals, special offers and other discount information Subscribe.
It may be unstable and unsafe, and maybe I just got a defective one but this one “blew up” like the reviews said. The other 3W is wasted as heat.

Spend a little more or in some cases, less and buy something that can actually be adjusted and calibrated without requiring the nerves of a bomb defusal technician.

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.
Sponsored products related to this item. I then saw that one of the diodes had busted open and the solder had melted. Ships from and sold by TangLiHua-us. I wired it up and was trying to adjust the output voltage. Question on LM Ask Question. Enter your destination to get a shipping estimate.
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.
