TPS53319: the PGood performance for the device

Part Number: TPS53319


Hi team,

My customer wants to use the device in the system. When they check the PG performance. The PG will go to low when the Vout still above 90%Vo.

The waveform is the shutdown waveform, we have checked the Vin=6v, EN=1.3V. Vo not drop to much, but the PG drop to 0. Do you have some ideas about the phenomenon? Thanks.

The waveform is below.
