  2. GR8210 Features ● 工作电压范围:5V~450V ●支持四种调光方式:开关调光、脉冲信号(PWM)调 光、线性调光(0~0.5V)、可控硅调光 ●全电压输入恒流精度可控制在2%以内 ●多重保护功能:LED开路保护、LED短路保护、过 电流保护、过温度保护 ●高低压(220V/110V) 电流补偿 ●可设置的LED电流高达0.8安培 ●可省略的降压电容器 (Buck capacitor) ●非隔离架构 ●较少的外围器件，两种封装供客户选择(SOP-8)及(DIP-8)

  3. GR8210优点 1.  省略整流后滤波电容,高低压 (220V/110V) 定电流误差值仍小于5% 2. 加上整流后滤波电容,全电压输入,输出恒流精度可控制在3% 以内 3. 输出正负极直接短路,不会爆,不会烧晶体管. 4. 最小可点亮 LED 颗粒数: 三颗.不会爆,不会烧晶体管. 5. 耐 Surge 8KV,IC 不会死.     6. 支持四段开关调光、无须外兜器件. 7.支持可控硅调光功能

  4. GR8210 Typical Application Circuit

  5. HV9910 Typical Application Circuit

  6. HV9910特点 ●工作电压范围8V~450V ●只支持两种调光方式，线性调光(linear dimming) ，PWM 调光（PWM dimming） ●过温保护，过流保护功 ●非隔离架构 ●较少的外围器件，两种封装供客户选择(SOP-8)及(DIP-8)

  7. HV9910缺点 ●没有短路保护功能 ●全电压输入恒流精度较差，大于7% ●VIN直接接高压，市电波动很容易烧坏IC
