非隔离AC-DC

MT7828D是一款工作于零电流导通，峰值电流关断的临界导通模式（ CRM）高精度LED恒流控制芯片，主要应用于非隔离降压型LED电源系统。临界导通模式确保了MT7828D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，确保了系统具有95%以上的峰值效率。 电感电流谷值为零的临界导通模式确保了输出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。对电感量变化不敏感，可以使用工字电感。芯片内部集成高压功率MOS管，使用JFET供电，无需启动电阻,外围电路简单，系统成本低。MT7828D工作电压宽，适合全范围交流输入电压或是60V - 400V直流电压输入。同时实现
