詳細介紹 文檔與工具 樣品及購買

        The SP1238F is a synchronous buck Regulator with output current to 3.1A.It is designed to allow for operating a wide supply voltage range from 8V to 30V. The internal compensation requires a minimum number of readily available standard external components.

        The SP1238F operates in the CV(Constant output Voltage) mode, and the OCP current value is set by current sensing power resisters.

        The SP1238F 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.
