L5989D 4 A continuous (more than 5 A pulsed) step-down switching regulator with synchronous rectification
The L5989D is a monolithic step down power switching regulator able to deliver a continuos output current of 4 A to the load in most of the application conditions limited only by the thermal performance . The device is able to deliver more than 5 A to the load for a maximum time which is dependent on the thermal impedance of the system and the specific operating conditions
