This schematic has a few functions to this circuit. This circuit takes voltages starting from 4V to a max. of 13V. It was an open source project I found online. I've redone this board's schematic. But when it came to de PCB design I kinda lost it. I got as close to sorting the components on the board, but I didn't know where to start connecting wires or how. I'm taking a little break, but if anyon...
WARNING Overvoltage-Reverse voltage protection with PTC and diode, Overcurrent Protection with PTC U2-U3.
Overdischarge protection with microcontoller.
Wrong setting may cause Injury or Overheating.
Overheating + Battery = Acidic gas + Fire + Expolosion. Only for indoor and well ventilated areas.

A schematic-only project to demonstrate how a bootstrap capacitor works. The overall circuit is a DC to DC Buck converter (see [Buck converter, from Wikipedia](https://en.wikipedia.org/wiki/Buck_converter)):
- The control signal is a 20kHz, 50% PWM wave.
- The power source is 12V DC.
- The MOSFET is a N-Channel, requiring a positive voltage between gate and source of at least 5V.
To simulate it,...
