Any suggestions on a switched mode battery eliminator for a 5v video system? I had an s-bec from firmtronics, but it stopped working today (for no good reason...). I generally run 8.4-9.6v and am looking for an efficient isolated switched power supply to give me 5v at 500ma or so.

I'm not sure if this will answer your question, but you can get a 5 volt regulator at Radio Shack for about $2.00

I think those are linear regulators. I really want the isolation and efficiency of a switched-mode converter. Thanks.

You might want to checkout the TI/PowerTrends switchers that Digi-Key stocks. They come in a variety of I/O voltages and current ratings. They also have friendly form factors.

You want a UBec available from Hobby-Lobby.

Thanks. I just ordered one. I tried using a linear regulator, but the noise from the pulses hitting the motor always gets through to the video signal. The s-bec worked for a while (firmtronics), hopefully the u-bec will last longer!

That's weird about the Sbec giving out... I use one on the servos of my helicopter, hope it doesn't give out while I'm in the air!

I should probalby contact them. It would probably be out of warrenty but it's worth asking. It just quit, very strange. Remember my problem with auto-iris? One of the surface mount caps on the camera came loose. I tacked in a replacement last night and solved the problem. Man those SMD parts are tough to work with without the right equipment!

Good catch on the iris problem, I'm glad it was just a matter of a loose cap.

I have the right equipment and it's STILL hard
