So I have been using some small audio amplifier ics in the tda series because they are good and easy to use but I have never had to power one with more than 24v. I am wanting to look into using a chip that requires about 35-40v supply but I can't find a transformer that is past 24v and am not looking to spend a lot of money. Recently I heard about dc-dc converters and am wondering if what I am thinking they do is what they actually do. From what I am getting they can take a low voltage at a lot of amps and convert it to adjustable high voltage with less amps. Is this correct?
So I want to try useing a tda chip that I would normally use a small transformer going to rectifier and using the center tab as ground, But instead sending the dc from the regulator through a dc-dc converter so I have enough voltage to power the chip and still use the center tab as ground.
I have NO experience with dc-dc converters so I don't know what you can and can't do with them and that's why I am asking if this would work.
I was looking at a module like this: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=111121366040&fromMakeTrack=true&ssPageName=VIP:watchlink:top:en
