Hi,

I have a question about the PG (Power Good) pin of TPSM861252 and TPSM863257.

1) There was no description of Power Good on the data sheet. Could you give me the waveform showing the relationship between the PG pin and the Vout pin?

2) Does the PG pin output Low when the VFB becomes a fault?

Best Regards,

Nishie
