DK124 Power Management IC 24W DIP-8

Description

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, and high voltage starting circuit are integrated into his DK124 IC. So that to save external circuit, component use and cost. Also size and weight of the product is reduced. It is specially suitable for price sensitive flyback switch mode power supply
