Hi
Im designing a 12-20V SMPS boost converter switching at 28Khz and I am not entirely sure on how to select the inductor size.
Do I use V = L x di/dt ?
where t would be ton of the power switch and V would be (20-12) = 8 V ?
Would I plug in values for the inductor and choose for the best di?
If so what is an acceptable ripple current? The output current is 2.5A
Thanks for any help you can provide!
