可控硅調(diào)光

MT7896是一款工作于零電流導(dǎo)通，峰值電流關(guān)斷的臨界導(dǎo)通模式（CRM，Critical Conduction Mode）高精度LED恒流控制芯片，主要應(yīng)用于BUCK-BOOST LED電源系統(tǒng)。MT7896支持高功率因數(shù)的應(yīng)用，PF可達到0.8以上。\n臨界導(dǎo)通模式確保了MT7896可以控制功率開關(guān)在電感電流為零時刻開啟，減小了功率管的開關(guān)損耗。電感電流臨界導(dǎo)通控制模式結(jié)合母線電壓補償，確保了輸出LED電流的高精度，并且具有良好的線性調(diào)整率和負載調(diào)整率。對電感量變化不敏感，可以使用工字電感。\nMT7896芯片內(nèi)置600V高壓功率MOS管,外圍電路簡單，系統(tǒng)成本低。\nMT7896同時實現(xiàn)了 ? 兼容可控硅調(diào)光\n? 支持高PF應(yīng)用，PF達到0.8以上\n? 寬范圍的調(diào)光兼容性\n? 調(diào)光深度可低于1%\n? 調(diào)光曲線符合NEMA SSL6標準\n? 內(nèi)置600V功率MOS管\n? 高精度LED恒流電流\n? 逐周期峰值電流控制\n?
