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 欢迎联系深圳市上大科技有限公司 李先生 1368649250 QQ：3537970767
