Anyone know about TPS3513? I m building a power supply. I need to do a power good circuit. i do not understand the PGI pin of tps3513. Can anyone please tell me or guide me?
I think that it is there so that a signal from the transformer can be connected to the TPS3513 to make sure that the power good signal stops as soon as possible when the mains fails, before regulated voltage starts to reduce.
With only a cursory reading of the data sheet, it looks to me that PGI is like an ENABLE input. It shuts the TPS3513 down if something upstream thinks there is a problem (missing ac?)

My project is building an atx power supply. The input of my circuit is from an external PSU, therefore i do not have a transformer.. So, can u tell me where do i connect to? Thanks
