L5988D

The L5988D 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.The input voltage can range from 2.9 V to 18 V. The device is capable of 100% duty cycle operation thanks to the embedded high side PMOS switch which doesnt need external bootstrap capacitor to be driven.The internal switching frequency is adjustable by external resistor and can be set continuously from 100 kHz to 1 MHz. The L5988D can also be synchronized to an external frequency signal driven to the SYNCH pin I/O pin.
