DK124 is an off-line switching power supply chip, the maximum output power of 24W. Unlike the PWM controller and the external discrete power MOS combination solution, the DK124 integrates a PWM controller, a 700V power transistor and a primary peak current detection circuit, and uses a patented self-powered technology that can omit the auxiliary supply winding, Simplifies peripheral applications, reduces the number of originals, circuit size and weight, especially for cost-sensitive flyback switching power supplies.
