TPSM53604: TPSM53604

Hi,

Let me look into this with the team to see if there are any specs to quantify this delay time between VOUT being 94% and when PGOOD pulls high.

Hi,

What specific details were you looking for with this? 

Attached is an image from the validation team for a 12Vin/5Vout @3A:

As you pointed out the delay time of PG asserting high is roughly 3ms which appears typical here. I would expect the TPSM53604 to perform like this straight out of box.

Hi Jimmy, 

we have a sequence requirement, we use PG of TPSM53604 to enable next rail, and next rail need output OK in 5ms after TPSM53604's Vo ready.

It seems TPSM53604 can not meet this requirement.

Do you have any suggestion to meet our requirement with this long delay time?

Hi,

Just wanted to clarify that the PG signal is to show when the VOUT output is within nominal range. When the PG signal goes high is when the "Vo is ready" is how I would interpret this signal. However if this still does not meet your requirement, what is  your input/output and loading requirements? 

Perhaps I can find an alternative power module that can meet your needs.

Jimmy
