STMicroelectronics L5989D
The L5989D is a monolithic step down power switching regulator able to deliver a continuous 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. The input voltage can range from 2.9 V to 18 V.| Part No. | L5989D |
