The SP1231FL is a synchronous buck Regulator withoutput current to 3.1A.It is designed t'o allow for operatinga wide supply voltage range from 5V to 30V. The internalcompensation require∏s a minimum number of readilyavailable standard exte¥rnal components.The SP1231FL operates in the CC(Constant outputCurrent) mode or CV(Constant outpu¥t Voltage) mode, andthe OCP current value is set by current sensin↑g powerresisters or setting non power resisters.The SP1231FL is suitable f€or the DC/DC switching powerapplications when requested∏ the current limit function.The devices are available in SOP-8L pa§ckage and requirevery few external devices for operαation.
