I'm a firm believer that if it is working and well within operating=20
parameters, leave it alone lol.

If it is working without excessive heat in your application then you should=
=20
be fine.

Dom,

But lower is better, only because of the heat generated in the linear
region, correct?  So at my given frequency, and other parameters, if
heat/power consumption is already low enough, there's not other reason
to need to go lower, is there?

Cheers,
