Hi, I'm doing a 3.3V design with TPS5420 these days. I'm trying to understand the open loop gain of TPS5420 buck circuit. However, with limited info from datasheet, it's difficult for me to figure out a transfer function that could match well with the bode plot shown in WEBENCH. Is there any doc that could explain how to get the transfer function that could match with the bode plot in WEBENCH? That will help a lot for me to understand the stability performance of this chip. Thanks a lot.
