Analog Devices Inc. DC2351A Demo Circuit for LT8228 Controller
Analog Devices DC2351A Demonstration Circuit is for the LT8228 Controller, a high voltage, high-efficiency synchronous buck or boost DC/DC converter. It is designed to have 36V to 56V on one side and 8V to 14V on the other. It can supply a 35A maximum output current in buck mode and delivers 7A of current in boost mode. The demo board features the LT8228EFE controller. This part can seamlessly transition from bucking to boosting. With built-in circuit breaker function and other protection features, the LT8228 is ideal for high-reliability systems requiring N+1 redundancy or other protections in industrial, automotive, medical, military, and avionics applications. The DC2351A is designed to be paralleled with other DC2351A boards to increase the total output current. With adequate heatsinking or airflow, the output current can be increased.Features
