Dear friends,
I'm trying to design a step down buck converter. I have couple of issues here to discuss.
Let me give you a brief idea on what I'm working on:
- The input voltage is 15 to 30 DC volts, and the output is 5 volts.
- The output current is 5 Amps.
I can figure the duty cycle, I ripple, and all that stuff EXCEPT! I was trying to find inductance, but couldn't figure out how to determine frequency!
I wanna know what determines frequency and how to calculate it in order to find the value of components (inductance and capacitance).
another issue is the variable input. If I have a variable input then the duty cycle will be an interval of numbers!
Please I need head ups on finding frequency
Thanks
