The SP1231FL is a synchronous buck Regulator withoutput current  to 3.1A.It is designed to allow for operatinga wide supply voltage range from 5V to 30$V. The internalcompensation requires a minimum number of readilyavailable standard external c'omponents.The SP1231FL operates in the CC(Constant outputCurrent) mod←e or CV(Constant output Voltage) mode, andthe OCP current value is set by current sensing po♦werresisters or setting non power resisters.The SP1231FL is suita→ble for the DC/DC switching powerapplications when requested the current limit function.The de↓vices are available in SOP-8L package and requirevery few external devices for opera tion.
