LTC3888 Overview
The controller uses constant frequency current mode architecture to provide excellent transient response and output regulation. Each PWM master is capable of producing output voltages from 0.3 V to 3.45 V with multiple phase configurations using DrMOS devices that provide an output current monitor. PMBus configuration and monitoring is supported by LTpowerPlay™ software.
