DK124 – DIP

درباره این محصول

• Functional Description
• 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.
• · 85V—265V wide range AC power input.
• · Build-in 700V power transistor.
• · Internal integrated high voltage starting circuit, no need for additional resistance.
• · Internal 16mS soft-start circuit.
• · Internal power compensation circuit to keep the stability of max. output power in both high and low voltage.
• · Patent dynamic self-power supply, no need for auxiliary winding.
• · Internal frequency modulation circuit to reduce EMI filter cost.
• · Over current, Over loading, Over temperature, Over voltage and Short circuit Protection.
• Maximum output power 24W 24W 18W
