DC2479A-A

DC2479A-A demonstration circuit 2479A-A features the LTM®4650EY, the high efficiency, high density, dual 25A, single 50A switch mode step-down power module regulator. DC2479A-A is configured as dual-phase, single-output, which can deliver up to 50A maximum. The board design with minimum components to demonstrate this high efficiency, high density µModule. The availability of the LTM4650EY in a compact 16mm × 16mm × 5.01mm BGA package make it ideal for use in many high-density point-of-load applications.
