Frequency on UCC2804D

Max Power1
Prodigy 80 points

Hi, 

I want to use the UCC2804D to regulate a DC/DC converter. After reading datasheet, I'm a bit confused about frequency of the PWM that I can generate. 

I set the frequency of the oscillator with Rt and Ct on RC pin, following the given equation. 

For example, if I choose Rt=22kOhm and Ct=1nF, I will have 68kHz frequency. Is this the frequency of PWM, that I will use at the input of gate drivers?

Thanks,
