线性驱动芯片ME8628在线性驱动方案中发挥什么作用？
线性LED驱动方案的优点是线路简单、无电感器件、无EMI干扰、可靠性高、适合全贴片生产工艺等，广泛应用于在LED照明领域。
由于线性驱动方案的架构特点，使得系统的输入、输出功率受市电电压变化的影响比较大。下面两组示意图说明了典型的线性LED驱动系统的功率受电源电压波动影响的原理。
第一组图是整流桥后加电解电容的系统电路及电流、电压波形。
可以看到因为整流桥后加了电解电容，使得VIN电压为一近似的直流电平，因此流过LED以及AC电源的电流也为直流。当市电AC电压升高时，VIN电压也随之升高，而LED灯串的压降近似为恒定值，因此加在恒流IC上面的电压增加，使得IC功耗增加，温度升高。而因为LED灯串的电压和电流都没有变化，所以LED输出功率维持不变，而系统的输入功率增加，整个系统的效率降低。
第二组图是另一种线性驱动架构，即整流桥后不加电解电容的情况。
在这种情况下，VIN电压为交流半波，当VIN电压高于LED灯串压降时，LED被点亮，流过由恒流IC所设定的电流；当VIN电压低于LED灯串压降时，LED电流为零。因此流过LED及AC电源的电流为具有一定占空比的脉冲电流。同样，当市电AC电压升高时，VIN电压半波的幅度也相应增加，这使得VIN电压超过LED灯串压降的时间段增加，LED电流的占空比增加，从而平均电流增加，这使得LED的输出功率和AC电源的输入功率都会增大。
LED照明系统的输入功率增加会使得灯具的发热增加，整灯温度升高，使得LED灯珠更容易发生光衰，寿命降低。同时发光效率也会降低，节能效果下降。而LED输出功率随输入电压的波动更会造成光照强度忽明忽暗，影响照明使用体验。在电网质量欠佳的国家和地区，线性照明系统的以上问题尤为突出。
微盟电子推出的带恒功率调节功能的线性驱动芯片ME8628，可以较好地解决线性照明系统功率随电源电压波动的现象。其工作原理是通过VS脚到OUT脚之间的电阻检测OUT端的电压变化，相应的调节恒流值的大小，在OUT电压升高时降低恒流值，以达到在电源电压发生波动时输入或输出功率基本恒定的目的。
下图是加入恒功率调节功能后的VIN电压和LED电流波形，可以看到随着VIC电压的升高，ILED电流的占空比增大，同时ILED电流幅度降低，从而使得平均电流维持基本不变。通过调节VS电阻的阻值可以调节电压补偿的幅度，从而能够适应不同的系统架构，在关心的电压波动范围内达到理想的恒功率效果。
下面两组图分别是ME8628应用于整流桥后加电解电容和不加电解电容的系统时的电路图，以及带和不带恒功率调节的效果对比。从对比效果看，加入恒功率调节功能后在220V-260V电压变化情况下功率变化幅度大幅减小，仅在3%以内，达到了较好的恒功率效果。
微盟电子推出的带恒功率调节功能的线性驱动芯片ME8628能够通过调节VS检测电阻，在各种线性驱动架构下实现较好的恒功率调节效果，从而起到优化照明体验，保护系统，延长灯具使用寿命的目的。
