Functional Pin Description

Pin No.

4, 1, 5, 8

3, 2, 6, 7

Pin Name

Pin Function

ISEN [1:4] P Positive Current Sense Pin of Phase 1, 2, 3 and 4.

ISEN [1:4] N Negative Current Sense Pin of Phase 1, 2, 3 and 4.

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

CORE VR loop external ramp slope.

RSET

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

amplifier.

COMP

Multi-Phase CORE VR Feedback. 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

Connect a resistor and a capacitor from this pin to GND to improve DVID

performance. Short this pin to GND if this function is not needed.

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 the IMON pin is connected to ground with another

CC_SENSE

IMONFB

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

resistors.

ADD

VR Address Setting Pin.

VCLK

VDIO

ALERT

Synchronous Clock from CPU.

Controller and CPU Data Transmission Interface.

SVID Alert Pin (Active Low).

Internal Bias Current Setting. Connect this pin to GND via a resistor to set the

internal current.

IBIAS

SETINI

CORE VR V

Setting.

INITIAL

SETINIA

AXG VR V

INITIALA

ADC Input for Multi-Phase CORE VR Maximum Temperature Setting. This pin

is also used for AXG VR’s offset selection.

TMPMAX

ADC Input for Multi-Phase CORE VR Maximum Current Setting. This pin is also

used for CORE VR’s offset selection.

ICCMAX

ICCMAXA

ADC Input for Single-Phase AXG VR Maximum Current Setting.

Single-Phase AXG VR Current Monitor Output Gain External Setting. Connect

this pin with one resistor to AXG rail V

connected to ground with another resistor. The current monitor output gain can

be set by the ratio of these two resistors.

, while IMONA pin is

CCAXG_SENSE

IMONFBA

IMONA

Single-Phase AXG VR Current Monitor Output. This pin outputs a voltage

proportional to the output current.

Address Flip and DVID Slew Rate Setting. Set the pin to GND if fast slew rate=

10mV/μs and slow slew rate = 2.5mV/μs is used.

SR_ADDF

OFSA

AXG VR Output Voltage Offset Setting.

Return Ground for Single-Phase AXG VR. This pin is the negative node of the

differential remote voltage sensing.
