It is a synchronous step-down regulator with an output current of 3.1A
The SP1289EF is a synchronous step-down regulator with a 3.1A output current. It is designed to operate over a wide input voltage range of 4.5V to 30V. Internal compensation requires a minimal number of external components.
The SP1289EF operates in either CC (constant output current) or CV (constant output voltage) mode, with the OCP current value set by a current sensing power resistor.
The SP1289EF is suitable for DC/DC switching power supply applications requiring current limiting functionality. These devices come in an ESOP-8L package and require few external components for operation.Features
