原邊控制，帶有源PFC的離線LED控制器

MP4021A是一款原邊控制離線LED照明控制器。 它采用SOIC8封裝，可為隔離式單功率級照明應(yīng)用提供高功率因數(shù)和精確的LED電流。其專有的實(shí)時(shí)電流控制方法可通過原邊信息精確控制LED電流。通過減少副邊反饋組件和光耦合器，大大簡化了LED照明系統(tǒng)的設(shè)計(jì)。MP4021A集成了功率因數(shù)校正功能，采用臨界導(dǎo)通模式，減少了MOSFET開關(guān)損耗。它具有極低的啟動(dòng)電流和靜態(tài)電流，可降低總功耗，并為照明應(yīng)用提供高效率解決方案。MP4021A具有的多重保護(hù)功能極大地增強(qiáng)了系統(tǒng)可靠性與安全性。這些保護(hù)功能包括過壓保護(hù)（OVP）、短路保護(hù)（SCP）、逐周期限流保護(hù)、VCC欠壓鎖定保護(hù)（UVLO）和自動(dòng)重啟熱保護(hù) ? 無需副邊反饋電路的實(shí)時(shí)電流控制\n? 獨(dú)特的架構(gòu)可實(shí)現(xiàn)出色的線性調(diào)整率\n? 在通用輸入電壓下提供0.9高功率因數(shù)\n? 臨界導(dǎo)通模式可實(shí)現(xiàn)高效率\n? 20μA超低啟動(dòng)電流\n? 1mA低靜態(tài)電流\n? 輸入欠壓鎖定保護(hù)（UVLO）\n? 逐周期限流保護(hù)\n? 過壓保護(hù)\n? 短路保護(hù)\n? 熱保護(hù)\n? 采用 SOIC8 封裝;
