Configuring the device
Note:
Note:
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;
170kΩ to SGND: LS MOSFET
Sense.
Filter with 100pF(max).
SSOSC / REF
VID_SEL
VID7 to VID0
SSEND /
PGOOD
It allows programming the soft-start time TSS.
See “Soft start” Section for details.
Resistor RSSOSC vs. SGND.
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 7).
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” (25µA pull-up)
Short to SGND: “0”
Soft Start end signal set free after soft-start has Pull-up to anything lower than
finished. It only indicates soft-start has finished. 5V.
VID pull-ups / pull-downs, VID voltage thresholds and OUTEN thresholds changes
according to the selected DAC: See Table 4 for details.
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.
270kΩ to SGND: Inductor
Sense;
OPEN: LS MOSFET Sense;
Filter with 100pF(max).
SSOSC / REF
VID_SEL
The reference used for the regulation is
available on this pin.
Not Applicable
Filter with 47Ω - 4.7nF vs.
SGND.
Need to be shorted to SGND.
VID7 / DVID
VID6
Pulled high when performing a D-VID transition.
The pin is kept high with a 32 clock cycles delay.
Not Applicable
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” (12.5µA 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.
VID pull-ups / pull-downs, VID voltage thresholds and OUTEN thresholds changes
according to the selected DAC: See Table 4 for details.
