The SP1231FL is a synchronous buck Regulator withouλtput current to 3.1A.It is designed to allow for operatinga wide≤ supply voltage range from 5V to 30V. The internalco®mpensation requires a minimum number of readilyavailable standard €external components.The SP1231FL operates in the CC(Constant outputCurrent) mode or CV(C≤onstant output Voltage) mode, andthe OCP current value is  set by current sensing powerresisters or setting non power resisters.The SσP1231FL is suitable for the DC/DC switching powerapplications when requested the current limi↕t function.The devices are available in SOP-8L package and requireveφry few external devices for operation.
