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 T
SS
.
See “Soft start” Section
for details.
Resistor R
SSOSC
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
(
Table

).
VID7 to VID0
They allow programming the Output Voltage
according to
Table 6
and
Table 7
.
Dynamic transitions managed,
See “Dynamic
VID transitions” Section
for details.
Open: Logic “1” (25
μ
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.

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.
270k
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
VID transitions” Section
for details.
Open: “0” (12.5
μ
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.
