General Description
      SM2087 is a high power factor linear constant current LED driver which is applied to LED lighting. Through the distinctive constant current control technology,  it  realizes  that constant current accuracy  is  less  than ±5% and output current is adjustable through external resistor. High power factor and low harmonic distortion are the particular features.  
The system is simple without transformer and electrolysis capacitor. Therefore, LED lighting batch job can be realized.
