USB EZ-PD Type-C

I'm making my own PD power adaptor with CCG3PA. This is an internal block diagram and application circuit of CCG3PA.

It is important to ensure that the circuit works steadily. So we need loop compensation consisting of these components circled in green in figure two. In order to calcaculate the exact value for these compenants, I need to know the exact value of the resistor circuled in red in the first figure according to the mathematical model for this type of topology.

Could any one help me?

Hi,

You can take a look into AN218238.

The internal resistor divider are 200 kΩ and 68 kΩ.
