Question about MP5515 PGB and PGS pins

DC-DC Power Converters
1

In the MP5515 datasheet, the PFI pin is defined as open-drain, but PGB and PGS are not. Interestingly, the Electrical Characteristics table treats PGB and PGS as if they are open-drain outputs. If these pins are standard CMOS outputs, the V_OH and V_OL levels should be specified, yet they are absent from the table. Could you clarify the output structure of the PGB and PGS pins?

Hi Murphy,

The PGB and PGS are not open-drain. The high and low threshold can be found in the EC table under PGB and PGS threshold:
