非隔離AC-DC

MT7814BD是一款工作于零電流導通，峰值電流關斷的臨界導通模式（CRM，Critical Conduction Mode）高精度LED恒流控制芯片，主要應用于非隔離降壓型LED電源系統(tǒng)。\n臨界導通模式確保了MT7814BD可以控制功率開關在電感電流為零時刻開啟，減小了功率管的開關損耗，確保了系統(tǒng)具有95%以上的峰值效率。電感電流谷值為零的臨界導通模式結合經過輸入母線電壓補償后的峰值電感電流，確保了輸出LED電流的高精度，并且具有良好的線性調整率和負載調整率。對電感量變化不敏感，可以使用工字電感。\n芯片內置高壓功率MOS管,外圍電路簡單，系統(tǒng)成本低。\nMT7814BD工作電壓寬 ? 臨界導通模式，對電感不敏感\(zhòng)n? 峰值效率高達95%以上?\n? 高精度LED恒流電流\n? 逐周期峰值電流控制\n?
