TPS56628: Is there any recommended condtion of rise time and fall time of VIN power?

Part Number: TPS56628

Hi Expert,

My customer is asking us if there is recommended operating condition of rise time and fall time of VIN power as TPS56628 specification. Do you have such values?

I have never considered this kind of power up/down requirement for DC/DC converter product like TPS56628 before. Of course, we have to provide stable VIN power for normal operation. However, I thought that such slew rate of power up/down doesn't cause any irregal behavior of TPS56628 internal circuit.

May I have your advice to answer to the question from the customer?

Thanks and regards,
Ikoma
