Functional Pin Description

Pin No.

Pin Name

Pin Function

Multi-phase CORE VR channel quick response time setting and initial voltage

(V ) setting.

QRSET

INITIAL

Place a resistor and a capacitor from this pin to GND to enhance DVID

performance. Short this pin to GND if not use.

DVIDA

5, 4, 8

6, 3, 7

ISEN [1:3] N

ISEN [1:3] P

Negative Current Sense Pin of Phase 1, 2, 3 for CORE VR.

Positive Current Sense Pin of Phase 1, 2, 3 for CORE VR.

Multi-Phase CORE VR Ramp Setting. This is used to set the multi-phase

CORE VR loop external ramp slope.

RSET

COMP

Multi-Phase CORE VR Compensation Node. This pin is the output node of the

error amplifier.

Multi-Phase CORE VR Feedback Input. This is the negative input node of the

error amplifier.

Return Ground for Multi-Phase CORE VR. This pin is the negative node of the

differential remote voltage sensing.

RGND

Place a Resistor and a Capacitor from this Pin to GND to enhance DVID

Performance. Short this pin to GND if not use.

DVID

OFS

Output Voltage Offset Setting.

Current Monitor Output. This pin outputs a voltage proportional to the output

current.

IMON

Current Monitor Output Gain External Setting. Connect this pin with one

resistor to CPU V

while IMON pin is connected to ground with one

CC_SENSE

IMONFB

another resistor. The current monitor output gain can be set by the ratio of

these two resistors.
