hi, today I found a toy which had 3.3F 2.5v capacitor in it. now I want to design a circuit that charges the capacitor to 2v and then cut the supply. I would be using 5v supply(from mobile chargers).
here are some ideas that pop into my mind;
1. Use LM393 comparator with fixed reference on of its input.
2. Use TL431 adjustable shunt regulators to turn of a mosfet on and off.
