DATASHEET ISL8120 Dual/n-Phase Buck PWM Controller with Integrated Drivers FN6641 Rev.3.00 July 20, 2016 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 synchronize to an external clock signal for frequency synchronization and phase paralleling applications.
