Hello all,
This is my first post here so here goes. I am into DCC trains and I am looking to amplify the output of a DCC Decoder. The DCC Decoder puts out either a positive or negative signal (drives a DC motor) and the DC voltage can vary from -24V to +24V (and anywhere in between) and I would like to simply amplify the current. Is there a single IC that can handle 8A continuous (peak of 30A) or a similiar circuit for amplifying this type of signal? Thanks for all of your help.

That's a good bit of current.

Have you checked out OpenDCC?

Here is an open project for a booster:

Much of the site is in German, but if you use Google Chrome translating to English is as easy as clicking a button.

Lots of links in this Wiki entry: http://en.wikipedia.org/wiki/Digital_Command_Control
