TPS54394: Are the two converters phase interleaved or not?

Josh Heiner

Part Number: TPS54394
Other Parts Discussed in Thread: TPS65279

In searching for dual synchronous buck converters on TI's website, I wanted to see only parts with phase interleaving, where the second buck is 180 degrees out-of-phase with the first. The TPS54394 parametrics show that it has this feature:

I couldn't, however, find any mention of this feature in the datasheet. The other TI parts I've looked at with this feature do mention it prominently in the datasheet.

Does this part have phase interleaving or not? If not, TI should really correct the parametrics for this part.

Thanks,

Josh

Josh,
This device uses D-CAP mode instead of Peak Current Mode, so do not support phase interleaved. Yes, will submit request to correct the parametrics for this device.
If you are seeking phase interleaved devices, please refer TPS65279.

Thanks Jason! That's what I needed to know. While you're at it, your web team should examine the other parametrics as well; there are many parts which show up in a search for synchronous converters which are not synchronous.
