Analog Devices DC2787A Demo Board for LTC7821 Controllers delivers 12V/100A with the input voltage from 40V to 60V. This board highlights the LTC7821 hybrid step-down synchronous controller with an architecture that blends a soft-switching switched-capacitor topology with a traditional step-down converter. This gives excellent efficiency in comparison to traditional switching architectures. The external MOSFETs of the board switch at a 400kHz fixed frequency and can be programmed from 200kHz to 1.5MHz. This complete set of features make the demo board an extremely efficient polyphase hybrid step-down converter.

The powerful 1Ohm N-channel MOSFET gate drivers of LTC7821 maximise efficiency and are able to drive multiple MOSFETs in parallel for higher power applications. This demo board offers a cost-effective solution for nonisolated intermediate bus applications in power distribution, datacom, and telecom and for emerging 48V automotive systems.
