Power Integrations Flyback Converter Power Switch IC 8-Pin DIP-B 6W 700V Operating Current 750mA LNK364PN

Power Integrations LNK364PN is a Flyback Converter Power Switch IC in an 8-pin DIP-B package providing a power rating of 6W and capable of operating at currents up to 750mA with a maximum supply voltage of 700V. This device is engineered for efficient power management applications, incorporating a 700V power MOSFET, oscillator, simple ON/OFF control, and frequency jittering to minimize EMI interference.

The LNK364PN features a high-voltage switched current source, cycle-by-cycle current limiting, and thermal shutdown circuitry for robust protection in demanding electrical environments. It operates directly off the DRAIN pin, eliminating the need for additional bias winding circuitry. Its universal input range supports worldwide operation, making it suitable for diverse industrial and commercial power management systems.

The device includes fully integrated auto-restart functionality to ensure safe operation during short circuit or open loop conditions, reducing output power by 95% under fault conditions. It meets high voltage creepage requirements between the DRAIN and all other pins, ensuring safety and reliability in printed circuit board designs.

Typical applications include power supplies, power adapters, and other switching power supply designs within industrial, laboratory, and commercial settings. The robust operating temperature range from -40°C to 150°C and through-hole DIP-B mounting facilitate easy integration into various electronic equipment.

Key features like frequency jittering for EMI reduction, accurate hysteretic thermal shutdown, and simple ON/OFF control without loop compensation simplify design and improve system reliability. The package dimensions are 9.83 mm in length, 6.6 mm in width, and 3.68 mm in height with a total of 8 pins.
