Demonstration circuit 2155A is available in two configurations. The DC2155A-A is a dual output synchronous step-down converter featuring the LTC®3886IUKG, a dual-phase current mode controller. The DC2155A-B is a single output synchronous step-down converter that operates with four phases: two from the LTC3886IUKG and two from LTC3870EUFD, a phase extender. Both versions have a PMBus interface and digital power system management functions.
