General Description 
        The SP1233FL  is a synchronous buck  Regulator  with output current to 3.1A.It is designed to allow for operating a wide supply voltage range from 5V to 32V. The internal compensation requires  a minimum number  of readily available standard external components. 
        The  SP1233FL  operates in the CC(Constant output Current) mode or CV(Constant output Voltage) mode, and the OCP current value is set by current sensing  power resisters or setting non power resisters.   
        The SP1233FL is suitable for the DC/DC switching power applications  when requested the current limit function. 
        The devices are available in SOP-8L package and require very few external devices for operation.
