Other Parts Discussed in Thread: TPS563200,
I checked the old device like TPS563200, which has clear spec function description about OVP as below, but we didn’t find it in TPS563203’s datasheet.

But in datasheet, Non-latch for OV, OT, and UVLO protection. This OV protection means what? Can you tell me in ECO mode, why when output higher than target, it will naturally turn off both HS and LS FET.
Because ECO has zero cross detection. Once FB higher than REF, high side will be turn off, as existing of ZC detection, LS will not turn on.
It is related to D-CAP control, so I say it is a nature OV.
I don't know much about D-CAP, can you share some information links, can you briefly talk about the working method of the D-CAP structure on the BUCK circuit, for example, when the upper and lower tubes are turned off, how does FB affect the conduction of the tubes?
