ISL8120规格书详情
The ISL8120 integrates two voltage-mode PWM leading-edge
modulation control with input feed-forward synchronous buck
PWM controllers to control a dual independent voltage
regulator or a 2-phase single output regulator. It also
integrates current sharing control for the power module to
operate in parallel, which offers high system flexibility.
The ISL8120 integrates an internal linear regulator, which
generates VCC from input rail for applications with only one
single supply rail. The internal oscillator is adjustable from
150kHz to 1.5MHz, and is able to synchronous to an external
clock signal for frequency synchronization and phase
paralleling applications. Its PLL circuit can output a
phase-shift-programmable 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 channel
from overloading/stressing due to system faults or phase
failure. The undervoltage fault protection features are also
designed to prevent a negative transient on the output voltage
during falling down. This eliminates the Schottky diode that is
used in some systems for protecting the load device from
reversed output voltage damage.
