Hi Mownika,

This blog provides the basics on PFC with and without input voltage sensing.

https://e2e.ti.com/blogs_/b/powerhouse/posts/is-pfc-possible-without-input-voltage-sensing?

This presentation goes more in-depth into our two primary PFC controller types, CCM and Transition Mode (TM) also known as Critical Conduction Mode (CrM)

The UCC28019 is in our CCM family of PFC controllers and utilizes input voltage sensing.
