非隔离AC-DC

MT7727EK是一款工作于临界导通模式（CRM，Critical Conduction Mode）的高精度LED恒流控制芯片，主要应用于85Vac~265Vac的非隔离降压型的LED电源系统。MT7727EK采用自主设计的高压片内供电技术实现了无VCC电容以及启动电阻，且芯片内置高压功率MOS管，外围电路简单，系统成本低。可支持高频应用。临界导通模式确保了MT7727EK可以控制功率开关在电感电流为零时刻开启，减小了功率管的开关损耗，确保了系统的高效率。电感电流谷值为零的临界导通模式结合经过输入母线电压补偿后的峰值电感电流，确保了输出LED电流的高精度，并且具有良好的线性调整率和负载调整率。 • 无VCC电容及启动电阻\n• 宽输入电压范围\n• 高精度LED恒流电流\n• 逐周期峰值电流控制\n• 前沿消隐控制\n• 过温自动调节\n• SOP7封装;
