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

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…

If you just want an off-the-shelf solution you may want to try to get a DC-to-DC converter from a company like Vicor. Look at: http://cdn.vicorpower.com/documents/datasheets/ds_vi-j00.pdf
which offers up to 100W supplies in a half brick. However, many times these companies offer many different outputs and inputs, but do not stock non-standard one, but it may be worth a try.
If you want to build your own as one replier suggested, ti.com or linear.com both have chips, circuits and on-line software to design supplies. Try National's (recently bought by Texas Instruments) WEBENCH at http://www.national.com/ and input the data into Webench Designer. With your input and output requirements they have about 7 or 8 different solutions including the LM3481MM/NOPBLM3481MM/NOPB from another replier.

Why don't they make these nice new parts as through hole or better yet monsterous so an old hog like me can bolt them to a 2x4 and solder house wiring to the pins?
