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.
