Hi, I am currently using the Design Tool for the TPS61199 LED Backlight Driver and I wanted some clarification how the gain margin gets calculated in the design tool. Usually gain margin is difference between 0dB and the gain where phase is -180 deg. But in the tool the gain margin is calculated as the difference between 0dB when phase is 0 degree. I am unsure if there is on offset in the curve or calculation that is driving this. Can someone clarify this?
