Hi, team

our customer using TPS65987D in their smart speaker and in order to control the standby power(IQ), they needs to change the sink PDO from 20V to 5V when enter the standby mode.

I am not sure whether we can using the i2C to adjust the sink 20V to 5V while the TPS65987 already in 20V sink.

Could u help to give some suggestions?

Thanks.
