APFC非隔離AC-DC

MT7855BS是一款高功率因數(shù)、非隔離LED驅(qū)動(dòng)芯片。 它通過采用浮地、高端檢測，降壓式開關(guān)電源的架構(gòu)實(shí)現(xiàn)了全周期檢測。MT7855B工作在準(zhǔn)諧振模式，同時(shí)使效率和抗電磁干擾的性能都得到提升。\nMT7855BS通過內(nèi)部集成的高壓供電電路供電，無需啟動(dòng)電阻和供電二極管。MT7855B內(nèi)置補(bǔ)償電路，節(jié)省了COMP管腳及COMP電容。MT7855B通過內(nèi)部集成THD補(bǔ)償電路，可以滿足更低THD需求。\nMT7855BS內(nèi)部集成了多重的保護(hù)功能，比如過壓保護(hù)、過流保護(hù)、過溫補(bǔ)償?shù)鹊?，提高了可靠性，并且所有保護(hù)均具體自恢復(fù)功能。內(nèi)置600V高壓MOSFET，精簡了外圍電路。\n \n? ? 單級功率因數(shù)調(diào)制（PF>0.9）\n? 高壓供電，無需啟動(dòng)電阻及供電電路\n? 內(nèi)置補(bǔ)償電路，無需COMP電容\n? 集成THD補(bǔ)償電路，THD<15%\n? 高次諧波失真抑制\n? 高精度的LED輸出電流 (±3%)?\n? 優(yōu)異的線性調(diào)整度和負(fù)載調(diào)整度 (±2%)?\n? 準(zhǔn)諧振工作模式?\n? 多重保護(hù)機(jī)制\n?
