Product Description
Power Integrations LNK3314D-TL Link Switch is a highly integrated Flyback topology power management IC designed for efficient AC-DC conversion with 10W output power capacity and a maximum output current of 170A. This 8-pin SO-8C surface mount device incorporates a 725 V power MOSFET, oscillator, and multiple protection features onto a single chip.
The device supports lossless zero crossing signal generation which is typically used for system clock and timing applications. Its frequency jittering capability reduces EMI filter requirements, simplifying system design.
Additional features such as soft-start limit system component stress during power-up, while hysteretic thermal shutdown provides robust protection against overheating. Fast current limit and input/output overvoltage protection enhance reliability and operational safety.
Designed for industrial, electronic, and power management applications, the LNK3314D-TL performs reliably over a temperature range from -40°C to 150°C, suitable for demanding electronic components and power conversion environments.
The compact SO-8C package dimensions are 4.9 mm in length, 3.9 mm in height, and 1.75 mm in width, allowing for efficient PCB layout and assembly. Features a built-in 725 V MOSFET for power conversion efficiency. Generates lossless AC zero crossing signals for precise timing applications.
Uses a Flyback topology for power supply design flexibility. Includes hysteretic thermal protection and fast current limiting. Operates within wide temperature range for industrial use. Compact surface mount 8-pin SO-8C package for convenient PCB integration.
Suitable for power conversion in electronic devices, industrial automation, and power supply designs, this Link Switch IC integrates multiple functions to reduce component count and simplify system design.
