Is there any information available concerning the ability of the error amplifier in UCC2800 to drive capacitive loads? I have a circuit that pulls the error amplifier low during certain fault conditions. It is connected to a trace that is about 5 inches long. The circuit oscillates at 1.2 MHz when the 5 inch trace is connected to the amplifier output. The oscillation does not occur when the trace is disconnected. Adding 100 pF to the amplifier output while the 5 inch trace is connected causes the oscillation frequency to change to 800 kHz. It appears that the issue is capacitance related but I do not know how to determine what amount of capacitance can be reliably tolerated.
Thanks.
