TPS65218D0: nPFO takes 400us to trigger, but datasheet says 25us

Thomas Frederick

Part Number: TPS65218D0
Other Parts Discussed in Thread: AM3351,

Tool/software:

We are using the TPS65218D0 with the AM3351. We've measured 400us for the nPFO signal to be asserted from the time the PFI input drops below the 800mV threshold. See attached. Please advise. Thank you.

Hi Thomas,

Would you be able to send a file of your schematic so I may take a closer look?
You may also send it over email or direct message if privacy is a concern.

Thanks,
Sarah
