UC2845A: Using COMP pin as a control port

Part Number: UC2845A

Tool/software:

I would like to connect the FB pin of UC2845A to GND and input a feedback signal from the secondary-side into the CMP pin to control the PWM output.

In this case,  CMP pin is connected to GND without any resistor, Is the CMP pin current-limited?

 

If there are any other potential issues, please let me know.
