See Table 12 and Table 13 for details about the codification of the command and the data
stream.
6.1.2
Overvoltage threshold adjustment (OV_SET)
This command allows to adjust the overvoltage threshold independently for CORE and NB
Sections. The default OVP threshold value of +250 mV over the reference is adjustable, in
200 mV steps up to +850 mV above the reference for CORE and +650 mV above the
reference for NB.
See Table 12 and Table 14 for details about the codification of the command and the data
stream.
Table 14.
OVP_SET command - threshold codification
6.1.3
Switching frequency adjustment (FSW_ADJ)
This command allows to adjust the switching frequency for the system in +/-10% steps
across the main level defined by the OSC pin. Switching frequency margining may benefit
the system from the thermal and performance point of view.
See Table 12 and Table 15 for details about the codification of the command and the data
stream.
Table 13.
OVRSPD command - offset codification (1) (2)
1.
Offset is added with an OTF VID transition above the programmed VID.
2.
Maximum regulated output voltage is internally limited to 2.8V maximum: regardless the offset over VID
reference the IC does not allow to reach an higher voltage.
