LM22680 / Self Synchronization with other DC/DC converter

TPS54540 can be synchronized to an external clock.  But it does not support the same type of synchronization as LM22680.

Hi John,

I'm Sonoki and working with Ogane at Macnica Japan.

I understand that TPS54540 can be synchronized to an external clock, so now it should be discuss if LM22680 can operate as Master to provide clock signal to slave devices. I think we should wait for response from SVA team.

Yes we will need to do that.  It is not clear from the datasheet, but I believe the LM22680 does not output a clock signal.  In fact, i bet that the "self synchronized" LM22680 still requires an external clock to operate, but I could be wrong.  The datasheet soes not say one way or the other.  Lets see what SVA has to say.

Hi John,

Yes, I also have the same understanding. I believe that LM22680 does not output a clock signal...

Let wait the comment from SVA team.

Hi John,

Thank you for quick response. I got it.
