LT8228 Bidirectional Buck/Boost Controller

Analog Devices Inc. LT8228 Bidirectional Buck/Boost Controller is a 100V constant-current or constant-voltage synchronous buck or boost controller with an independent compensation network. The direction of the power flow is automatically determined by the LT8228 or externally controlled. The input and output protection MOSFETs protect against negative voltages, control inrush currents, and provide isolation between terminals under fault conditions such as switching MOSFET shorts. In buck mode, the protection MOSFETs at the V1 terminal prevent reverse current. In boost mode, the same MOSFETs regulate the output inrush current and protect themselves with an adjustable timer circuit breaker.
