Pin Name

Pin Function

PWM3

PWM Output for CORE rail VR of Channel 3.

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

ISEN[1:3]P

Positive Current Sense Inputs of Multi-Phase CORE rail VR Channel 1, 2 and 3.

7, 10, 6

ISEN[1:3]N

Negative Current Sense Inputs of Multi-Phase CORE rail VR Channel 1, 2 and 3.

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 OCS, DVID threshold and

ICCMAX for CORE rail VR.

SET2

2nd Platform Setting. Platform can use this pin to set RSET, QRTH, QRWIDTH and

DVID width for CORE rail 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 will output 0.8V.
