Voltage regulator enable input. A high level logic signal on this pin enables the VR.
Open-drain output to indicate the regulator is ready to supply regulated voltage. Use an appropriate external pull-up
resistor.
Output current monitor pin. IMON sources a current proportional to the regulator output current. A resistor
connected from this pin to ground will set a voltage that is proportional to the load current. This voltage is sampled
with an internal ADC to produce a digital IMON signal that can be read through the serial communications bus.
Thermal overload output indicator.
Thermistor input to the VR_HOT# circuit.
Window voltage set pin used to set the switching frequency. A resistor from this pin to COMP programs the
switching frequency (18k Ω gives approximately 300kHz).
This pin is the output of the error amplifier.
This pin is the inverting input of the error amplifier.
This pin switches in an RC network from VOUT to FB in PS1 and PS2 modes to help improve transient performance
and phase margin when dropping phases in low power states. There is a switch between the FB2 pin and the FB
pin. The switch is off in the PS0 state and on in the PS1 and PS2 states. If this function is not needed, the pin can
be left open.
Individual current sensing input for Phase 3. Leave this pin open when ISL6353 is configured in 2-phase mode.
Individual current sensing input for Phase 2. When ISEN2 is pulled to 5V VDD, the controller will disable Phase 2,
and the controller will run in 1-phase mode.
Individual current sensing input for Phase 1.
Output voltage sense pin. Connect to the output voltage (typically VDDQ) at the desired remote voltage sensing
location.
