Other Parts Discussed in Thread: TPS53219

Hi All,

Now our customer has evaluated TPS53219 and then they found that the PGOOD keep Low for approx. 10sec after VDD and VOUT power down. We guess that PGOOD is turned to High (Hi-Z) sooner after power down. Can you comment why it stay such long time?

Best Regards,
