LED驅(qū)動(dòng)-隔離驅(qū)動(dòng)+PFC; ? 內(nèi)置單級(jí)有源功率因數(shù)校正，PF>0.9 \n原邊反饋，無需光耦，TL431等器件\n高性能的線電壓調(diào)整率和負(fù)載調(diào)整率\n±3%輸出電流精度\n內(nèi)置650V功率MOSFET\n啟動(dòng)電流(10uA)\nINV反饋電阻值高，功耗低\n多重保護(hù)功能\n^LED開路/短路保護(hù)\n^電流采樣電阻開路保護(hù)\n^逐周期原邊電流限流\n^芯片供電過壓/欠壓保護(hù)\n^自動(dòng)重啟功能\n^過熱調(diào)節(jié)功能\n封裝：SOP-8/DIP-8\n;

 M8912是一款隔離式、單級(jí)有源功率因數(shù)校正的高精度原邊反饋LED恒流控制芯片，適用于范圍（85-264V）輸入的反激式隔離LED恒流電源。\nM8912集成有源功率因數(shù)校正電路，具有很高的功率因數(shù)和較低的總諧波失真。工作在電感電流臨界連續(xù)模式，功率MOS管處于零電流開通狀態(tài)，減小開關(guān)損\n耗。M8912工作于原邊反饋模式，無需次級(jí)反饋電路，即可實(shí)現(xiàn)高精度輸出恒流控制。
