Table 11.
Intel mode configuration (See Note).
Pin
Function
Typical connection
DAC / CS_SEL
It allows selecting the Intel Mode and,
furthermore, between Inductor or LS MOSFET
current reading.
Static info, no dynamic changes allowed.
SGND: Inductor Sense;
170k
to SGND: LS MOSFET
Sense.
Filter with 100pF(max).
SSOSC / REF
It allows programming the soft-start time TSS.
Resistor RSSOSC vs. SGND.
VID_SEL
It allows selecting between VR11 DAC or
VR10.x + 6.25mV extended DAC.
Static info, no dynamic changes allowed.
Open: VR11 (Table 6).
Short to SGND: VR10.x
VID7 to VID0
They allow programming the Output Voltage
according to Table 6 and Table 7.
Dynamic transitions managed, See “Dynamic
Open: Logic “1” (25
A pull-up)
Short to SGND: “0”
SSEND /
PGOOD
Soft Start end signal set free after soft-start has
finished. It only indicates soft-start has finished.
Pull-up to anything lower than
5V.
Table 12.
AMD mode configuration (See Note).
Pin
Function
Typical connection
DAC / CS_SEL
It allows selecting the AMD mode and,
furthermore, between Inductor or LS MOSFET
current reading.
Static info, no dynamic changes allowed.

to SGND: Inductor
Sense;
OPEN: LS MOSFET Sense;
Filter with 100pF(max).
SSOSC / REF
The reference used for the regulation is
available on this pin.
Filter with 47
- 4.7nF vs.
SGND.
VID_SEL
Not Applicable
Need to be shorted to SGND.
VID7 / DVID
Pulled high when performing a D-VID transition.
The pin is kept high with a 32 clock cycles delay.
Not Applicable
VID6
Not Applicable
Needs to be shorted to SGND
VID5 to VID0
They allow programming the Output Voltage
according to Table 9.
Dynamic transitions managed, See “Dynamic
Open: “0” (12.5
A pull-down)
Pull-up to V > 1.4V: “1”
SSEND /
PGOOD
Power Good signal set free after soft-start has
finished whenever the output voltage is within
limits.
Pull-up to anything lower than
5V.
