DK812 : The DK812 is a single stage AC-DC transformer controlling IC. It integrates 700V high voltage power transistor and primary peak current detecting circuit. It also includes Active Power Factor Correction, Primary Side Current Regulation, Output Voltage Control, Self-Power supply and LED loading circuit auto detection functions, can avoid LED loading damage. Its integrated Active Power Factor Correction circuit can reach high power factor and low harmonic distortion. And because of its highly integrated MOS circuit design, lots of external components are saved, transformer design is simple, only two windings is needed for the transformer in isolated circuit and only one winding is needed in no.
