PGOOD output timing of LTC3644

Category: Hardware
Product Number: LTC3644

Hi, 

 

In the graph "Start-Up Operation" on page 6 of the LTC3644 datasheet, PGOOD goes High 2.5ms after Vout rises.

However, page 9 states that the PGOOD output goes high immediately after achieving regulation

The PGOOD output timing on this graph appears to be slow, is this correct?

 

Regards,
