DK912
DESCRIPTION
The DK912 is a primary side flyback type AC-DC Switch Mode Power Controlling IC. It integrates 700V high voltage power transistor and primary side peak current detecting circuit. It also includes Primary Side Constant Current Regulation, Constant Voltage Control, Self-Power supply circuit and Output cable pensation functions. Because of its highly integrated CMOS circuit design, lots of external ponents are saved, transformer design is simple, only two windings are needed in transformer for isolated circuit designs.
