You can use the DK124 is an offline switching power chip with a maximum output power of 24W. Different from PWM controller and external
A discrete power MOS combination solution, the DK124 integrates a PWM controller, 700V power tube and primary peak
Current detection circuit, and the use of the auxiliary power supply winding can be omitted patented self-power technology, so greatly simplified
Peripheral application circuits reduce the number of components, circuit size and weight, especially for cost-sensitive flyback switches
