The LTC3874 is a dual-output multiphase synchronous step-down slave controller that generates currents of up to 300A when paired with a companion master controller, by extending the phase count in multiphase applications. The LTC3874 operates with true current mode control and enables the use of sub-mΩ DC resistance (DCR) power inductors without any sense resistor in order  to maximize converter efficiency and increase power density.
