DEscriptION
        The SL3018 is a monolithic stepdown switch mode controller with a programmable output current limit.It achieves continuous out put current over a wide input supply range with excellent load and line regulation.
        The maximum output current can be programmed by sensing current through an accurate input sense resistor.
        It can out put constant voltage. Internal thermal shutdown, cycle-by-cycle currentlimit protect ion.
        The SL3018 requires a minimum number of readily available standThe chip is available in 8-pin SOIC8 packages.
