I am looking for a way to limit the total amount of energy out of an audio circuit. I have read
it can be done using a PWM scheme. I am unable to use some IC chips that do this in a
package, such as the Philips SA570, because I need to keep my current user very low, and
I am using 2.5 volts to run the show.

Any thoughts?
