UCC28950: UCC28950 error amplifier specification

Part Number: UCC28950

Hello,

I want to use the UCC28950 as a voltage follower. I read the one post that covered this question. The post was from 2014, and the answer did not provide any details, so I would like to ask the question again. The main concern I have is the stability of the error amp at unity gain. Is it stable? What is the phase margin and gain margin at the UGBW (3MHz). I can't find any graphs of the error amp response on the data sheet. I want to make sure that when I cascade the external error amplifier with the internal error amplifier of the UC28950, the circuit is still stable. I may have to adjust the normal compensation network to achieve stability with the added pole from the voltage follower. 

Thanks, 

Chuck Sampson
