[Kynix]

Recently, I have read a article about switching power supply which written by my follower, and I have little confused the third part of it(enclosed the url: https://www.kynix.com/Blog/458.html), especially the calculation formula with its figures, it is imperfect and has some stuff missing.

Cheers
