AC-DC隔离产品

 LIS8516B 是一款专用于 LED 恒流驱动的控制芯片，通过采用专有的初级侧 LED 恒流控制技术，使得系统架构得到了最大程度的精简。它不但省去了传统二次侧控制所需的光耦和 431 等反馈器件，而且还进一步省去传统初级侧控制架构中用于实现反馈的辅助绕组，反馈电阻以及为 IC 供电的整流二极管等无源器件，使系统成本得到极大程度的降低。更为关键的是，LIS8516B 对输入及输出电容的容量极为不敏感，因此可用小容量的贴片电容替代大电解电容，大大提高了系统寿命。由于采用漏感供电，LIS8516B 系统的输出电压范围得到极大的拓宽，同一驱动系统可以驱动 24~30 颗串联 LED，方便系列机种应
