DC>DC power supply for DEQX

Antonyhu · 4th December 2011, 02:51 AM

Hi All,

Im looking to build a DC>DC power supply for my DEQX which is currently in my car running off a pure sine wave inverter.

I would like to do it myself with a kit or design, but unable to find one on the net with the specs I need.

I need it to be stable and perform flawlessly.

11v-15v input
+/- 15v rails at .6 amps

Can anyone help me out with directions to a design or kit or design one for me that I can build. I have very good soldering skills and have made plenty of KITs in the past.

Thanks for any help.

Antony

perhaps the easiest way is to build the DC-DC converter off standard unit such as link below by Traco.

Thanks Calvin,

Would I just stick this on a board and provide 12v from the battery use the earth as the common earth for the outputs?

Simplest method would be something like this:

Digi-Key - 102-2367-ND (Manufacturer - VYB20W-Q24-D15-T)

There should be some protection from noise and transients on the 12V supply. An inductor, fuse, capacitors, transient absorber. And if you want a really clean 15V, use a higher voltage DC-DC converter followed by linear regulators.

If you can scrounge a smallish power amp with a good power supply but blown amp(s), that would be overkill as far as power goes. You might be able to use the supply as-is and just add linear regulators to drop the voltage. Or rewind the transformer secondary and adjust the feedback sensing for lower voltage.
