1. what is Buck converter?
A buck converter is a circuit that steps down a higher DC voltage to a lower DC voltage while increasing the curren, this buck converter is a fix buck converter that can't adjustable the output voltage . in this project we gonna to make buck converter that converter higher voltage to 5v
2. requirements
Lm7805
capacitor ceramic 0.1uF
capacitor 220uf
Tblock
copper
៣. Schematic Diagram
4. How does it work
1.First we put raw power in input (j1) if circuit have power .
2. all capacitor have the same duty to make circuit smooth and stable
3. Lm7805 is a heart of the circuit it the one that make a voltage drop to 5v
4. after lm7805 drop the voltage it will output at j2
