                                                                                                  LT8228 is a 100V bidirectional constant-current or constant-voltage synchronous buck or boost controller with independent compensation network. The direction of the power flow is automatically determined by the device 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 prevents reverse current. In boost mode, the same MOSFETs regulate the output inrush current and protects itself with an adjustable timer circuit breaker. It offers bidirectional input and output current limit as well as independent current monitoring. It is used in application such as dual battery automotive and industrial systems, high power system backup and supply stabilization, “N+1” redundant, high reliability power supplies, power interrupt protection system etc.
