TPS54561: internal VCC and min Toff time spec

Hi,

I will check with the internal system and design time to see if there are any called out spec for this device. 

As you've mentioned the datasheet doesn't provide any clear parameters/specs for what you are looking for.

When I get more information on this I'll get back to you.

Regards,

Jimmy

Hi Jimmy,

     Do you have any update of that? thanks!

Hi Feng,

I just sent out a reminder to the team again.

Hopefully they get back to me since they are in a different time zone.

Thank you for your patience.

Jimmy

Hi,

I just got confirmation that they will try to get back to my by the end of this week.

Again thank you for your patience. 

When I get more info on this, I will provide an update to you.

Hi Jimmy,

    I'd like to double check if we've got the data of VCC voltage and min Toff spec, and want to ask one more spec: VCC UVLO. thanks! 

Hi,

I just sent another reminder to the team.

Again thank you for your patience and sorry I couldn't get to this database and get you the information sooner.

These specs are not listed in the datasheet so only the designers can some idea of what these specs are.

Jimmy

Hi Jimmy, 

     Thanks for your update. I also want to check the BOOT charge output voltage for TPS54561. Because in 7.3.4, I can't understand this equation well, does it mean VBOOT-SW or VBOOT-GND? if it means VBOOT-SW, when Vin>11V, VBOOT-SW>8V, over spec; if it means VBOOT-GND, when Vin=20V, Vboot=14.76V< 20V Vin.

Thanks for your help.
