Configuring the device

29/70

Note:

VID pull-ups / pull-downs, VID voltage thresholds and OUTEN thresholds changes

according to the selected DAC: See Table 4 for details.

Note:

VID pull-ups / pull-downs, VID voltage thresholds and OUTEN thresholds changes

according to the selected DAC: See Table 4 for details.

Table 11.

Intel mode configuration (See Note).

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

Ω to SGND: LS MOSFET

Sense.

Filter with 100pF(max).

SSOSC / REF

It allows programming the soft-start time TSS.

See “Soft start” Section for details.

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

(Table 7).

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

µA 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).

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

Ω 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

Ω - 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

µA 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.
