ISL8120IRZEC

DC DC Switching Controllers Overview

The ISL8120IRZEC is a dual/n-phase buck PWM controller with integrated drivers, manufactured by Renesas Electronics Corporation. It features two voltage-mode PWM leading-edge modulation controls with input feed-forward for synchronous buck regulation. The device supports dual independent outputs or a 2-phase single output regulator. It includes current sharing control for parallel power modules and an internal linear regulator generating VCC from the input rail. The adjustable internal oscillator ranges from 150kHz to 1.5MHz and can synchronize to an external clock. A PLL circuit outputs phase-shift programmable clocks for expansion to 3-, 4-, 6-, or 12-phase configurations. Fault handshake protection prevents channel overloading during system faults or phase failure.
