TPS65987D: What is the source slew rate from PPHV1 to PPHV2?

Oliver Lin

Part Number: TPS65987D

Hi team,

Could you please share the information of the TPS65987DDH, customer would like to know that the what is the slew rate that switch from PPHV1(5V) to PPHV2(20V).

Customer application is a dock.

Best regards,

Hey Oliver,

I have a few clarifying questions. So

For your customers system PPHV1 and PPHV2 are both configured as a source?d
PPHV1 is connected to a 5V DCDC and PPHV2 is connected to a separate DCDC programmed to a constant 20V?

Hey Adam,

Yes, that is correct, PPHV1 and PPHV2 are both as source, and they have their own DC source, which means that 5V and 20 V are independent.

Hi Oliver,

Thank you for the confirmation. I don't think we have a specific value for the slew rate in this scenario. However, the slew rate will stay within the spec range as well as what is outline in the datasheet which is a max of 0.03 V/us.
