Simple single ended primary inductance converter (SEPIC) based on the MT3608 with a fixed output voltage selectable by the resistor values of the voltage divider.
TPS40057 is a high voltage synchronous buck controller with a wide input voltage range (8V to 52V). TPS40057 has a high degree of design flexibility and can provide a variety of user-programmable functions, including soft start, undervoltage lockout (UVLO), operating frequency, voltage feedforward, high-side current limit, and loop compensation.
This design is to input 12-24V. Design 3A insurance...
5Vbuck converter based on MC34063.
Based of [https://electronics.stackexchange.com/questions/504796/an-adjustable-power-supply-with-tracking?noredirect=1#comment1290490_504796](this) question and this Schematic i have tried this designing.
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...

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,...
