From the project
A collection of PCB design projects created using KiCad. This repository contains schematic designs, PCB layouts, 3D renders, and manufacturing files for various electronics projects.
This project demonstrates the design of a Boost Converter PCB using KiCad. The converter steps up a lower DC input voltage to a higher DC output voltage using a PWM-controlled switching circuit.
- PWM Signal Generator using LM555 Timer - DC-DC Boost Converter Stage
The PWM signal drives the MOSFET switch, allowing energy storage in the inductor and increasing the output voltage.
