is a synchronous buck regulator with output current up to 3.4a.
the sp1239ef is a synchronous buck regulator with output current up to 3.4a.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 sp1239ef 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.
the sp1239ef is suitable for the dc/dc switching power applications when requested the current limit function. the devices are available in esop-8l package and require very few external devices for operation.
