| Sep 14, 2023 at 6:30 | comment | added | Tim Williams | The opto itself can do drive, without a DC-DC at all; if you're just looking for an offhand solution, one could be constructed with a stack of photodiode or phototransistor (base-pin-available type e.g. 4N25) optos... but probably the charge pump is better, yeah. | |
| Sep 14, 2023 at 5:56 | comment | added | Samuel Snerden | I thought about that option as well, but I don't have the components on hand and I only need to turn on/off one mosfets. If i had a circuit with multiple switches then it would definitely be worthwhile to look into that. Also, I'd like to avoid inductors (and transformers), I don't have the materials to build them at the moment. | |
