隔離AC-DC

MT7946是針對LED照明應用而設計的驅動開關電源，采用無輔助繞組的原邊反饋技術，無需次級反饋電路，也無需補償電路。內部集成600V高壓功率開關，可調LED開路保護(OVP)使得系統方案簡潔可靠。\nMT7946采用美芯晟專利的恒流控制與補償技術，LED輸出電流精度達到±3%以內，具有優(yōu)異的線性調整率和負載調整率，且對變壓器繞組電感變化不敏感。\nMT7946同時實現了各種保護功能，包括逐周期過流保護(OCP)、LED短路保護(SCP)、LED開路保護(OVP)和過熱調節(jié)(OTR)等，以確保系統可靠地工作。? ? 內部集成600V功率管\n? 無需輔助繞組\n? 防潮可調LED開路保護\n? 交流輸入電壓范圍AC85V到AC265V\n?
