How can I step up from 12V to 14V for about 80 W?

Former Member
Former Member over 13 years ago

H

 

I want to run a projector from my 12V circuit.

The projector is 14V and 3.5 Amp -

I don't really want to use an inverter.

Is there a simple way to step up 12V to 14V ?

 

thanks v.  much

    Matt, Here you go, Use an LM3481MM/NOPB LM3481MM/NOPB : http://www.newark.com/national-semiconductor/lm3481mm-nopb/ic-n-ch-controller-msop-10/dp/84M8119?in_merch=Popular%20Power%20Management%20Products…

    What sort of projector and what sort of 12V circuit ?

     

    If the projector wants 14V DC it might work OK from 12V - check with the supplier (or just try it if you're feeling lucky).

     

    There is no way to efficiently convert 12V DC to 14V DC at 3.5A without using some kind of switching circuits - by the time you add all the necessary protection and emc precautions it won't be very simple.
