Pin Name

Pin Function

TSEN

Thermal sense input for CORE VR.

5, 6, 2, 9

ISEN[1:4]P

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

4, 7, 3, 8

ISEN[1:4]N

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

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

feedback to controller.

COMP

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

VSEN

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

output voltage.

RGND

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

voltage sensing.

SET1

1st platform setting. Platform can use this pin to set OCS, DVID threshold and

ICCMAX for CORE VR.

SET2

2nd platform setting. Platform can use this pin to set RSET, QRTH, QR width and

DVID width for CORE VR. Add to 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 outputs 0.8V.

16, 28, 30, 44,

No internal connection.

SET3

3rd platform setting. Platform can use this pin to set VR address, Zero load-line, AI

gain, Disable DVID compensation, Decrease GTU and SA ramp (only in maximum

phase = 1-phase), high frequency ramp, DVID slew rate.
