Pin Name

Pin Function

PGOOD

VR ready indicator.

TONSET

CORE rail VR on-time setting. An on-time setting resistor is connected from this pin

to input voltage.

TSEN

Thermal sense input for CORE rail VR.

8, 9, 5, 12

ISEN[1:4]P

Positive current sense inputs of multi-phase CORE rail VR channel 1, 2, 3 and 4.

7, 10, 6, 11

ISEN[1:4]N

Negative current sense inputs of multi-phase CORE rail VR channel 1, 2, 3 and 4.

Negative input of the error amplifier. This pin is for CORE rail VR output voltage

feedback to controller.

COMP

CORE rail VR compensation. This pin is the error amplifier output pin.

VSEN

CORE rail VR voltage sense input. This pin is connected to the terminal of CORE

rail VR output voltage.

RGND

Return ground for CORE rail VR. This pin is the negative node of the differential

remote voltage sensing.

SET1

1st platform setting. Platform can use this pin to set Enable Zero load-line, DVID

threshold and ICCMAX for CORE VR.

SET2

2nd platform setting. Platform can use this pin to set Ramp Setting, QRTH, and OCS

for CORE VR. Moreover, SET2 pin features a special function for users to confirm

the soldering condition of the controller under zero VBOOT condition. Connect the

SET2 pin to 5V and turn on the EN pin, if the soldering is good, both rails output

0.8V.
