Wiring the LM2596S

[LlamaBreath]

Hey fellow modders!!

First off, thought I might introduce myself, as per the low post count but the early join time - I have been vaping for a while, and modding for a little while, I am located in Australia and mainly use the Aussie Vapers Forum, but I notice and was told about the wealth of knowledge over here on ECF and thought I might come over and ask some advice on my latest mod building venture.


I see there are alot of people who have experience with using the LM2596S, (I noticed the sub forum, but cant seem to find the diagrams I am chasing) I am specifically using this one - The advice that I am after is simply wiring, I have a USB charge board and a LiPo cell battery I am wanting to hook up to it, with a standard 510 connection, a momentary PBS and a standard On/Off slide switch ( Three prong/terminal, like this ).

I have a pretty good knowledge of wiring in general, but I cant seem to find a simple diagram to instruct me as to the correct wiring for the desired set up I am after (a sealed unit, charged by USB, momentary fire switch, on/off power switch, 510 connection)


Cheers in advance if anyone has any links to a direct diagram that may help me (I find actually seeing things written out gives me a better success rate when it comes to soldering!! haha)

If you are going to use a 5v 2a wall plug to feed the power supply; you will get 3.5 volts max output. You need to supply 1.5 volts higher than you will use.

The board you are using has a 1.5 amp max output....ya really need to use the LM2596S...search ecf for LM2596s......lots of info....

Ok, I was planning on just charging it through the USB 2.0 or 3.0 ports of my PC, I am not sure I understand what you mean by supplying higher volts, I plan on having thia as a stand alone unit, not a passthrough via USB, just charged via USB.

I am pretty sure it is the LM2596S, that is what is has printed on the chip on the board.

Cheers for the replies!

If you look at the specs for that chip. It will state that the maximum output voltage will be 1.5 volts lower than the input. It is a step down converter. Therefore, USB is 5v. Your maximum output voltage while charging would be 3.5 v

You will need voltage detection so you don't over charge, diodes etc. a little beyond my scope of electronics.

Alright! Thanks for the advice! I will look into it.

I'm a DSWAD J3 guy myself for building mods. They are rugged little controllers. Another reason I like the Dswad J3 controllers for building my PVs. I had 2 that had messed up pots on them (my fault). I wrote the company an email and ask where I could get them. They said we will send you some. They pd. shipping too. They also said send them to us and we will fix them for you.
