Could you tell me the MODE pin input current and PGOOD pin leak current?
Reference value is OK.
MODE pin is pulled-up to PGOOD pin and PGOOD is pulled-up to VREG pin when device is used with FCCM. In this case, I think PGOOD high voltage level is influenced by MODE pin input current and PGOOD pin leak current. Our customer is going to use PGOOD signal to another external circuit, thus they is concerned about PGOOD high voltage level .
