恒压恒流、变换器芯片 SL3018

详情描述：

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　　Available in 8-Pin SOIC8 Packages　　深圳市森利威尔电子有限公司　　ShenZhen Senliwell Electronics Co.,LTD.　　TEL:075526786865Fax:0755 26991979　　欢迎有识之士取样实测，我司可提供技术支持。　　如有需要可联系13537575802（曾生）　　企业QQ：23553688773
