TPS53679: The phase adding / shedding setting is different from the actual measured value

Part Number:TPS53679

Hi TI,

We use TPS53679 as our CPU core power solution (VCCIN) with 3-ph setting.

We found the phase adding / shedding setting is different from the actual measured value while performing the efficiency measurement.

So I have two questions as below:

1. What kind of current information (I_avg or I_peak or I_valley) that TPS53679 uses for phase adding/shedding control?

2. Does the Iout_cal_gain calibration impact the current information that for phase control?

BR.
