Splitting 12v into 6v - Image1.jpg (0/1)

[[email protected]]

Hi,

To conserve space would I be able to use a 12v power source to power 2
pinhole cameras which require 6v each?

The cameras have a mini DC input which then attaches to a battery clip
on the battery pack

I've attached a small diagram of what I'm attempting to help
illustrate my question.

Should I plug in both cameras first then attach the battery?

Regards,

Sean

Don't connect them in series, the equation you think of works fine with 2
equal loads. The load of the cameras will "never" be equal you will most
likely destroy one and immediatly after that the other.
Why don't you use some kind of Voltage Regulator??? If you use the LM317 you
can make almost every Voltage needed.

Don't even _think_ about it.

There are basically two ways to do what you want; the first being to
use a linear regulator (something like an LM317) to drop the 12V
down to 6V. If the load of the two cameras is too great for a
single LM317 to handle, you could use a separate LM317 for each
camera, assuming the load from a single camera isn't too great.

Here's a link to the LM317 data sheet so you can check it out:

The other way is to use a buck regulator, which is a much better way
because it won't be wasting all the power the LM317(s) will.

Here's a link if you want to roll your own:

Thanks for the information, I will check this out.
