TPS22965-Q1: Fast discharge not working

Part Number: TPS22965-Q1
Other Parts Discussed in Thread: TPS22965

Hi there !

I have ordere some TPS22965NTDSGRQ1 samples to build a switching solution with quick discharge.

But I don't see a significant discharge when I pull the Enable low. It takes forever to discharge the 4u7 cap that is connected to the VOUT pins.

VIN in is 3.3V

I was wondering if I got wrong parts (not all of the TPS22965 have the quick discharge).

Can someone confirm that parts marked ZDXI do have the quick discharge function?

Any other idas what could be wrong?

Thanks

Pirmin
