The SP1231FL is a synchronous buck Regulator withoutput ®current to 3.1A.It is designed to allow for operatinga wide supply v←oltage range from 5V to 30V. The internalcompensation requires a minimum number of readilyavailable¶ standard external components.The SP1231FL operates in the CC(Con♦stant outputCurrent) mode or CV(Constant output Voltage) mode, andthe OCP§ current value is set by current sensing powerresisters or setting∑ non power resisters.The SP1231FL is suitable for tβhe DC/DC switching powerapplications when requested the current limit function.The devices are ava♥ilable in SOP-8L package and requirevery few external devices for operation.
