The ISL8120 integrates two voltage-mode PWM leading-edgemodulation control, with input feed-forward
synchronous buckPWM controllers, to control a dual independent voltageregulator or a 2-phase single
output regulator. It alsointegrates current sharing control for the power module tooperate in parallel, which
offers high system flexibility.The ISL8120 integrates an internal linear regulator, whichgenerates VCC from
input rail for applications with only onesingle supply rail. The internal oscillator is adjustable from150kHz
to 1.5MHz, and is able to synchronize to an externalclock signal for frequency synchronization and phase
parallelingapplications. Its PLL circuit can output a phase-shiftprogrammable clock signal for the system
to be expanded to 3-,4-, 6-, 12- phases with desired interleaving phase shift.The ISL8120’s Fault Hand
Shake feature protects any channelfrom overloading/stressing due to system faults or phasefailure. The
undervoltage fault protection features are alsodesigned to prevent a negative transient on the output
voltageduring falling down. This eliminates the Schottky diode that isused in some systems for protecting
the load device fromreversed output voltage damage.
