TPS53647: Output Ripple During Startup

Hirotsugu Kobayashi

Part Number: TPS53647
Other Parts Discussed in Thread: CSD95472Q5MC,

Hi, team.

A 4-phase converter was designed with TPS53647 and CSD95472Q5MC. 12Vin 0.85Vout.
I want to raise the output voltage from 0V with a constant slope, but it will rise up to 300mV stepwise.
How can I make the slope constant?
