A resistor placed from FS to ground will set the PWM switching frequency.

Use this pin to set up the desired soft-start time.

Peak current mode PWM control with adjustable slope compensation.
Precision resistor/DCR current sensing.
2-, 3- or 4-phase operation.
Adjustable phase dropping/diode emulation/pulse skipping for high efficiency at light load.
Phase dropping facilitated with companion FET driver ISL78420 (featuring tri-level input control).
Adjustable switching frequency or external synchronization from 75kHz up to 1MHz per phase.
Over-temperature/o.
