TL494/SG3525 as the PWM for class D

corrieb · 16th September 2006, 02:04 PM

Has anyone of you ever tried to use the TL494/SG3525 as the PWM for a low bandwidth (bass drive) Class D audio amplifier?

There are two threads trying to do exactly that:

"Class D amp using TL494"
"Looking for subwoofer classD using TL494"

Just look for TL494 on the Class D threads titles and you will find them. Don't know if they reached any working prototype, though.
