    • 5.5%~100% Dimming Range
    • CV Mode for Bias Supply at <2.5% Dimming Signal
    • Primary Side Control Eliminates the Opto-coupler
    • Valley Turn-on of the Primary MOSFET to Achieve Low Switching Losses
    • 300mV Primary Current Sense Voltage Leads to A Lower Sense Resistance thus A Lower Conduction Loss
    • Internal High Current MOSFET Driver: 0.20A Sourcing and 0.65A Sinking
    • Low Start up Current: 34μA Typical
    • Reliable Short LED and Open LED Protection
    • Power Factor >0.90 with Single-stage Conversion.(Analog Dimming Only)
    • RoHS Compliant and Halogen Free
    • Compact Package: SO8
