UCC28070: Does HF RMS current reach max in VIN_MIN

Part Number: UCC28070

Hello, Experts,

As I was reading the application note (https://www.ti.com/jp/lit/an/slua479b/slua479b.pdf) and learning about Interleaved PFC design using UCC28070, I came across the output capacitor selection section.

From Eq. (15), Eq. (16), VIN_MIN is used as a part of equation; does this mean that HF RMS current reaches its max value in the input voltage is equal to VIN_MIN?

Sorry to ask you a very basic question, but would like to know whether my understanding is correct. Also, it would be very helpful if you could provide us with helpful guides/app notes.

Thanks,

Masaru
