APFC非隔离AC-DC

MT7860是一款高功率因数降压型LED驱动芯片。工作在准谐振模式（QRM），大大降低了电流和电压的应力，同时使效率和抗电磁干扰的性能都得到提升。利用美芯晟特有的准全周期检测专利技术对LED输出电流进行检测，确保了LED输出电流的精度。\n\nMT7860通过解码PWM信号和模拟信号实现调节LED电流，从而实现智能调光。通过内部微调解码器实现LED电流的高精度和一致性。尤其在调光等级较低时，PWM控制方法从准谐振模式无缝地转入脉冲频率调制模式（PFM），从而保证了较小的输出电流和低开关损耗。\n\n另外，MT7860同时实现了各种保护功能，包括LED开路保护（OVP）、逐周期过流保护(OCP） • 单级有源功率因数校正（PFC>0.90）\n• LED电流精度高:±3%\n• 优异的线性调整度和负载调整度:±2%\n• 准谐振工作模式（QRM）\n• 多重保护机制\n• PWM调光（100:1）和模拟电平调光\n• 封装: SOP8;
