PSI#
Functional Pin Description
PSI#
Low load current indicator input. When asserted low,
indicates a reduced load-current condition. For ISL6260B,
when PSI# is asserted low, PWM2 will be disabled.
PGD_IN
Digital Input. When asserted high, indicates VCCP and
VCC_MCH voltages are within regulation. PGD_IN signal
high is needed for the CLK_EN# to be low and PGOOD to
be high.
RBIAS
147K Resistor to VSS sets internal current reference.
VR_TT#
Thermal overload output indicator.
NTC
Thermistor input to VRTT# circuit.
SOFT
A capacitor from this pin to Vss sets the maximum slew rate
of the output voltage. Soft pin is the non-inverting input of the
error amplifier.
OCSET
Overcurrent set input. A resistor from this pin to VO sets
DROOP voltage limit for OC trip. A 10µA current source is
connected internally to this pin.

sources current.
COMP
This pin is the output of the error amplifier.
FB
This pin is the inverting input of error amplifier.
VDIFF
This pin is the output of the differential amplifier.
VSEN
Remote core voltage sense input. Connect to micro-
processor die.
RTN
Remote voltage sensing return. Connect to ground at micro-
processor die.
DROOP
Output of droop amplifier. Output = VO + DROOP.
DFB
Inverting input to droop amplifier.
VO
An input to the IC that reports the local output voltage.
VSUM
This pin is connected to the current summation junction.
VIN
Battery supply voltage, used for feed forward.
VSS
Signal ground; Connect to local controller ground.
VDD
5V bias power.
