非隔離AC-DC

MT7817CD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恒流驅(qū)動(dòng)芯片，主要應(yīng)用于非隔離降壓型LED電源系統(tǒng)，并支持PWM/模擬電平調(diào)光。\n臨界導(dǎo)通模式確保了MT7817CD可以控制功率開關(guān)在電感電流為零時(shí)刻開啟，減小了功率管的開關(guān)損耗，確保了系統(tǒng)具有93%以上的峰值效率。\n電感電流谷值為零的臨界導(dǎo)通模式結(jié)合經(jīng)過輸入母線電壓補(bǔ)償后的峰值電感電流，確保了MT7817CD輸出LED電流的高精度，并且具有優(yōu)異的線性調(diào)整率和負(fù)載調(diào)整率，可以使用工字電感，并對(duì)電感量變化不敏感。\nMT7817CD工作電壓寬，適合 ? 內(nèi)部集成500V高壓功率管\n? 臨界導(dǎo)通模式，對(duì)電感不敏感\(zhòng)n? 支持PWM/模擬電平調(diào)光應(yīng)用\n? 最高93%以上的峰值效率?\n? 高精度LED恒流電流?\n? 逐周期峰值電流控制\n?
