TPS2663: relationship among OVP, UVLO and PGTH

Part Number: TPS2663

Hi Team

Are the OVP, UVLO setting and PGTH setting involved in each other?
Or is it completely irrelevant, is PGTH set only for PGOOD?
Thanks
Best regards,

    Hello Shidara-San,

    Voltage at PGTH is used for setting the PGOOD signal and also for deciding the behavior/startup of the device after transient on input. if voltage at PGTH is more than PGTH threshold, the device powers-up the output quickly (without dVdT control for output).
