Pin Function Descriptions
GND (Bottom Pad)
Signal common of the IC. Unless otherwise stated, signals are
referenced to the GND pin.
CLK_EN#
Open drain output to enable system PLL clock; goes active 13
switching cycles after V core is within 10% of V boot .
PGOOD
Power-Good open-drain output indicating when the regulator is
able to supply regulated voltage. Pull-up externally with a 680 Ω
resistor to VCCP or 1.9k Ω to 3.3V.
RBIAS
A resistor to GND sets internal current reference. A 147k Ω
resistor sets the controller for CPU core application and a 47k Ω
resistor sets the controller for GPU core application.
VR_TT#
Thermal overload output indicator.
NTC
Thermistor input to VR_TT# circuit.
VW
A resistor from this pin to COMP programs the switching
frequency (8k Ω gives approximately 300kHz).
2
COMP
This pin is the output of the error amplifier. Also, a resistor across this
pin and GND adjusts the overcurrent threshold.
FB
This pin is the inverting input of the error amplifier.
VSEN
Remote core voltage sense input. Connect to microprocessor die.
RTN
Remote voltage sensing return. Connect to ground at
microprocessor die.
ISUM- and ISUM+
Droop current sense input.
VDD
5V bias power.
VIN
Battery supply voltage, used for feed-forward.
IMON
An analog output. IMON outputs a current proportional to the
regulator output current.
BOOT
Connect an MLCC capacitor across the BOOT and the PHASE
pins. The boot capacitor is charged through an internal boot
