DC2888A Demo Boards

Analog Devices DC2888A Demo Board is engineered based on the LTC388x step-down controllers. The LTC388x step-down controllers are dual PolyPhase DC-DC synchronous switching regulator controllers with an I²C-based PMBus-compliant serial interface. The demonstration circuit 888A offers a synchronous secondary side control featuring the LTC3725 and LTC3706. When powered from a 36V to 72V input, a single DC888A-B supplies an isolated 5V at 40A in a quarter-brick footprint. Additionally, the DC2888A-A supplies 3.3V at 50A. If a higher output current is needed, multiple ADI DC888A boards may be stacked together using onboard connectors for a complete PolyPhase current-sharing solution.
