About LNK304PN, DIP-8B Integrated Circuit
LNK304PN, developed by Power Integrations and belonging to the LinkSwitch-TN family, is an AC-DC power control integrated circuit designed for low-power switched-mode power supply (SMPS) applications. The DIP-8B package structure enables easy use and reliable soldering in through-hole mounted designs.
This integrated circuit operates over the 85 – 265V AC universal input range, efficiently and stably converting mains voltage to direct current (DC) output. Its built-in 700V high-voltage MOSFET, oscillator, simple ON/OFF control structure, current limiting, thermal protection, and auto-restart circuits minimize the need for external components.
LNK304PN is specifically designed to replace linear regulators and capacitive dropper power supplies. This provides higher efficiency, lower power loss, reduced heat generation, and longer-lasting power supply solutions. The integrated frequency jitter feature reduces EMI (electromagnetic interference) levels and lowers additional filter costs.
The auto-restart feature protects the integrated circuit safely under fault conditions such as short circuit, overload, or feedback loss, preventing system damage. In this respect, LNK304PN is a reliable solution for continuous operation and long-term stability applications.
