I'have to build a buck converter with the following requirements:
$$\text{1) Input voltage (Uin): 12 Volt}$$ $$\text{2) Output voltage (Uout): 5 Volt}$$ $$\text{3) Voltage ripple (on the output) 0,1 Volt}$$ $$\text{4) Output current of 0,5 Ampere (when you short the output resistor)}$$
The Dutch word functiegenerator is a functiongenerator, that produces the input puls.
The MOSFET is a P-Channel MOSFET IRF9540n. And the voltage drop on the diode is 0.6 volts
The question I've are the following:
The formula for getting the right duty cycle (that you've to set on your fuctiongenerator) is that given by:
$$D=1-\frac{V_o}{V_{in}}$$
And how can I calculate the minimum value of my capicator and inductor?
Thanks in advance
