DK125 DIP-8 DC-DC Converter

Description

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. 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. Specifications: Pin Configuration: Applications: AC/DC power adapters. DVD/VCD/DVB power supply. Air conditioner power supply. Electromagnetic oven power supply. LED driver applications. TV/Monitor power supply. Household electrical appliance. Package Include: 1x DK125 DIP-8 DC-DC Converter Datasheet: DK125
