UCC2808A-1Q1: UCC2808A-1Q1:

Part Number: UCC2808A-1Q1

We would like to know the maximum frequency  (oscillator frequency  & switching frequency at OUTA) limit for UCC2808 IC .

As we have found schematic of one of the application note on TI website as shown below  (PMP9522),


Oscillator frequency Fosc= 1.41/RC  = 390.32kHz.


  But we see that the datasheet says 213kHz max.



We would like to have clear idea on what is the maximum oscillator frequency that can be set. And also what are values of R and C that can be used for that max frequency.

At this Max oscillator  frequency , what will be the output frequency ?



Thanks ,
