Demonstration circuit 2605A is a high efficiency, high density, single-output buck converter with 7V to 14V input range. The output voltage is adjustable from 0.5V to 1.5V, and can supply up to 120A of load current with a 1V output. The demo board features the LTC3884-1paired with a slave controller LTC3874-1 to provide a 4-phase buck converter solution. The LTC3884-1 is a dual output poly phase step-down controller for ultra-low DCR sensing with digital power system management. The LTC3874-1 is a dual PolyPhase® current mode synchronous stepdown slave controller. Please see LTC3884-1 data sheet for more detailed information.
