Hello,
I am looking for some support using the COMP pin to disable the PWM IC. I use the P-MOSFET to pull COMP to GND as suggested in the datasheet. The voltage of COMP initially stabilized at 3.38V. Then P-MOSFET is turned on, COMP pulled to GND through the P-MOSFET. Now the voltage of COMP drops to ~1V. To keep the P-MOSFET ON, the source-to-gate threshold shall be lower than 1V. The question is, to keep COMP pulled to GND, what's the suggested gate threshold for the P-MOSFET?
Thank you,
Alice
