Dear, Sir.
My customer is desgining their system to apply TPS62260-Q1 with EN pin is tied to VIN.
At this time, they are asking about the VIN ramp-up rate limitation.
1. VIH/VIL on EN pin are min. 1V & max. 0.4V. It means the unknown
voltage zone is wide as 0.6V. I suppose the slower VIN ranp-up rate
would not be good considering transient time.
I wonder my assumption is correct?
2. Please clarify the VIN ramp-up rate limitation if you have.
3. I just focusing EN pin threshold. If you have other concern about
slower VIN ramp-up rate, Please let us know.
Best Regards,
H. Sakai
