What I need is a photovoltaic optocoupler with serious CTR. The ones I
can get have CTRs like 0.5%. Power gain is better, but they make 8 or
so volts and I only need 3.3.

I recall someone once making some optocouplers with serious power
capability, but can't find them now.

A PV would sure be quiet.
