I might look that up--except that I had bad experiences with the IR
2110-type devices that incorporate a charge-pump for driving the "top"
circuit.  The electric field from my secondary (apparently) disrupted
that circuit; I thought it would be a nifty replacement for a transformer
but I had to go back to transformer-coupling instead.
