Functional Pin Description
PSI#
Low load current indicator input. When asserted low,
indicates a reduced load-current condition. For ISL6260C,
when PSI# is asserted low, PWM2 will be disabled.
PMON
An analog output. PMON sends out an analog signal
proportional to the product of VCCSENSE voltage and the
droop voltage.
RBIAS
147k Resistor to VSS sets internal current reference.
VR_TT#
Thermal overload output indicator.
NTC
Thermistor input to VR_TT# circuit.
SOFT
A capacitor from this pin to Vss sets the maximum slew rate
of the output voltage. It affects both soft start and VID
transitioning slew rate. Soft pin is the non-inverting input of
the error amplifier.
2
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.
ISEN3
Individual current sensing for channel 3.
ISEN2
Individual current sensing for channel 2.
ISEN1
Individual current sensing for channel 1.
FCCM
Forced Continuous Conduction Mode (FCCM) enable pin to
MOSFET drivers. It will disable diode emulation.
