Been listening to something over the last couple of days, knew the SB3 supply could be improved on, but the stock Touch switcher? Naa.
uhm..yes it can. Clean linear power supply can do it. Dont groan.. :) I wouldn't put pen to paper if it wasn't something special. What I'm using is a two box, linear psu custom designed by someone who knows his onions... A word from the designer... Why a two box solution? Well, the idea came from the fact that its a bit silly having a regulator thats several foot from the load its supplying. Just looking at the voltage across the load you can see the regulator its trying to control it at the end of a long stick. So the idea was to try and get the regulator as close as possible to the load. And after that thought, given that I have more control over both sides of the regulator, I thought something a bit more interesting than a stock three pin reg would be called for. The regulator in the little box isn't discrete as such because it uses a low noise op amp as a error amp and a descret mosfet to control the output. I can also pack some paralleled caps in there to try and get closert to a fast responding small regulator. First stage regulator and transformer out the way, final high speed low noise regulator close to the load. Just looking how the load voltage varies shows that you get at least a order of magnitude closer regulator than using a three pin regulator on the end of a wire. Common sense electrical engineering? I'm sure it measures well too... (I have no commercial affiliation with the product or its designer, just had a chance to hear an early example of it. I'm happy to recommend it. -- Gazjam ------------------------------------------------------------------------ Gazjam's Profile: http://forums.slimdevices.com/member.php?userid=18604 View this thread: http://forums.slimdevices.com/showthread.php?t=90742 _______________________________________________ Touch mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/touch
