Pin No

Pin Name

Pin Function

SET3

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

Anti-overshoot function and behavior, AI gain, Disable DVID compensation,

Decrease GTU and SA ramp (only in maximum phase = 1-phase), high frequency

ramp, DVID slew rate, and PSYS function for CORE VR and AXG VR.

SETA1

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

ICCMAX for AXG VR.

SETA2

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

DVID width for AXG VR.

IMON

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

loading current.

VREF

Fixed 0.6V Output Reference Voltage. This voltage is only used to offset the output

voltage of IMON pin. Between this pin and GND must be placed a exact 0.47

F

decoupling capacitor and a 1

 resistor.

IMONA

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

loading current.

VR_HOT

Thermal Monitor Output, this Pin is Active Low.

ALERT

SVID Alert. (Active low)

VDIO

VR and CPU Data Transmission Interface.

VCLK

Synchronous Clock from the CPU.

VR Enable Control Input.

VCC

Controller Power Supply. Connect this pin to 5V and place a decoupling capacitor

2.2

F at least. The decoupling capacitor is as close VR controller as possible.

IBIAS

Internal Bias Current Setting. Connect a 100k

 resistor from this pin tied to GND to

set the internal current. Don’t connect a bypass pass capacitor from this pin to GND.

RGNDA

Return Ground for AXG VR. This pin is the negative node of the differential remote

voltage sensing.

VSENA

AXG VR Voltage Sense Input. This pin is connected to the terminal of AXG VR

output voltage.

COMPA

AXG VR Compensation. This pin is error amplifier output pin.

FBA

Negative Input of the Error Amplifier. This pin is for AXG VR output voltage feedback

to controller.

36, 39, 40

ISENA[1:3]N Negative Current Sense Inputs of Multi-Phase AXG VR Channel 1, 2 and 3.

37, 38, 41

ISENA[1:3]P Positive Current Sense Inputs of Multi-Phase AXG VR Channel 1, 2 and 3.

TSENA

Thermal Sense Input for AXG VR.

TONSETA

AXG VR On-time Setting. A on-time setting resistor is connected from this pin to

input voltage.

DVD

Divided Input Voltage Detection of Power Stage. Connect this pin to a voltage

divider from input voltage of power stage to detect input voltage.

46, 47, 48

PWMA[1:3]

PWM Outputs for AXG VR of Channel 1, 2 and 3.

PS4

External Driver Enable Control. Connecting to driver enable pin. As received PS4

command, this pin will be low state.

50, 51, 52, 53 PWM[1:4]

PWM Outputs for CORE VR of Channel 1, 2, 3 and 4.

PGOOD

VR Ready Indicator.

TONSET

CORE VR On-time Setting. A on-time setting resistor is connected from this pin to

input voltage.

(Exposed Pad)

GND

Ground. The exposed pad must be soldered to a large PCB and connected to GND

for maximum power dissipation.
