In theory, if I did pull the gate of a p-channel mosfet to ground, would that not turn it on rather than off?
Why did you choose a target time of 50ns? We're not talking about switching at several MHz here, just a few tens of kHz.
Try disconnecting one end of the 47 ohm resistor and measuring the output from the TC4429 again
Also check that the ground pins of the TC4429 really are at 0v all the time, in case you have a bad joint.
What value resistor do you have between the TC2249 output and the mosfet gate?
