Halo, I am new in electronic.
My project is going to design of buck converter that can transfer from 28V to 5V for charging iPad. The attachment shows the calculation steps. And I know that the inductor cannot sustain too much current. Therefore, I decide to put maybe 8 or 9 inductors in parallel. Is the calculation correct for designing a buck converter?
And now I am in the stage of prototyping, I have bought the following components already. But I think maybe wrong....
- 1 x Arduino for control the MOSFET switch frequency
- 1 x Electrolytic Capacitor, 22µF, 10V, MS5 Series, RubyCon
- 8 x Inductor, 680µH
- 1 x NPN Power MOSFET, IRFP450, 14A, 500V, 190W
- 1 x Diode, MIC 1N4001, 50V, 1A
Is everything alright? Anyone could left some comments for me, please? Thanks for your help!!!!!
