PV gate drivers are nice, but they are slow turning on when supplying a lot of gate charge. The ADI parts, with internal power isolators, are expensive and insane power hogs.
So maybe we could separate the power transfer from the gate drive functions:
Another possibility would be to use the single PV driver, but blast the LED side with extra current at the turn-on edge.
Or just stick with my flyback gate driver.
Or maybe use a standard DC/DC converter as an isolated gate driver, if we could find a cheap one that was fast enough on/off and didn't waste a lot of power.
