DK

The DK1203 is a secondary side flyback type AC-DC Switch Mode Power ControllingIC. Withintegrated 700V high voltage power transistor, patented self-power supply circuit and integratedCMOS circuit design.

The DK125 is a secondary side fly-back type AC-DC Switch Mode Power Controlling IC. Designed with high integration CMOS circuit, it has protection functions for short circuit, secondary side open circuit, over temperature, over voltage and so on.

The DK124 IC is specially design for off-line switch mode power supply, maximum power is 24W. Different from PWM controller and external power separated MOS combination design, the PWM controller, 700V power transistor.

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.

The DK112 is specially design for low power switch mode control, it is widely use in small household electrical appliances.
