General Description The SP1233F  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  SP1233F  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 SP1233F  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.Features ?  5V ~ 32V Supply Voltage Range ?  36V Input Voltage Surge ?  32V Input Over Voltage Protection ?  2% Voltage Reference Accuracy ?  5% Constant Current Accuracy ?  External Optional Current Limit Mode ?  Programmable Frequency（60KHz ~ 1MHz） ?  Built in Adjustable Line-Compensation ?  Hiccup Short Circuit Protection ?  Duty Cycle Range (0~100%) ?  Internal Soft Start 3ms ?  CC/CV Mode Control ?  SOP-8L Package Applications ?  Car Chargers   ?  Portable Charger Devices   ?  DC/DC Converters with Current Limit   歡迎聯系深圳市上大科技有限公司     李先生  1368649250   QQ：3537970767
