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.
FEATURES Wide +8V to +85V Operating Input Range Programmable up to 8A Output Current when 12V input. Output Adjustable from 0.8V to +35V Programmable Output Current Limit without power loss OPower MOSFET Switch Mature output short protection circuit 85% Efficiency @ 1000mA (Vo=5V) when +75V input Fixed 200KHz Frequency Ouput up to 2A when +72V input Cycle-by-Cycle Over Current Protection
