Electric OU: TK-Akula 3V: DC-DC Chip Test 1

ERRATUM: At one point I say “milliVolts” when I should have said “milliAmps” when referring to the current limiting power supply set to 225 mA.

Thanks to slider2732 for the tip about the MC34063A chip that is found in the USB charger adapters which are available at the Dollar Tree stores for one dollar US. I immediately went out to the local store and bought one.

Here is some testing with the chip in place, showing some interesting behaviour.

I still don’t have the inductor in place. I am making the inductor on a TV flyback transformer core.
