    n 40-Pin (6mm × 6mm) QFN Package The LTC®3882 is a dual, PolyPhase DC/DC synchronous
    step-down switching regulator controller with PMBus
    compliant serial interface. It uses a constant frequency,
    leading-edge modulation, voltage mode architecture for
    excellent transient response and output regulation. Each
    PWM channel can produce output voltages from 0.5V to ...
