DK125 DIP-8 DC-DC Converter

DK125 DIP-8 DC-DC Converter

The DK125 DIP-8 DC-DC Converter is an advanced off-line switch mode power controller integrated circuit designed for efficient AC-DC conversion in flyback topologies. Manufactured by Anhui Dongke Semiconductor Co., Ltd., this CMOS-based IC integrates a high-voltage power transistor and essential control circuitry into a compact DIP-8 package, enabling simplified designs with minimal external components. It supports a wide input voltage range of 90-265VAC, making it suitable for universal mains operation without the need for voltage-specific adaptations. The built-in 700V high-voltage BJT handles power switching directly, while the patented self-power supply circuit eliminates the requirement for an auxiliary transformer winding, reducing complexity and cost in isolated output applications.

 Features: 

• 85V—265V wide range AC power input.
• Build-in 700V power transistor.
• Internal integrated high voltage starting circuit, no need for additional resistance.
