DK813
DESCRIPTION
The DK813 is a LED Driver IC designed specially for Non-Isolated high PFC BUCK circuit. It integrates 700V high voltage power transistor and primary peak current detecting circuit. It also includes Active Power Factor Correction, 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 Total Harmonic Distortion. And because of its highly integrated MOS circuit design, lots of external ponents are saved.
