    Hi，

    I have another question about TPS54821RHLR. In the datasheet, it mentioned that "If an application requires controlling the EN pin, use open drain or open collector output logic to interface with the pin" as below figure shown.

    Here, I just want to know whether could using CMOS push-pull output to interface with EN pin of TPS54821RHLR? 

    Thanks in advance!

    Best Regards!
