LNK304GN-TL General Description

The LNK304GN-TL is a low-power, high-efficiency off-line switcher IC from Power Integrations. It is specifically designed for use in AC/DC power supplies with output power ratings up to 8W. The IC incorporates a 700 V power MOSFET, a PWM controller, and a gate driver in a single package, providing a compact and cost-effective solution for power supply designs.The LNK304GN-TL features a built-in simple primary-side control (SPC) that eliminates the need for an optocoupler and secondary feedback circuitry, simplifying the design and reducing component count. It also offers a wide input voltage range of 85 VAC to 265 VAC, making it suitable for operation in a variety of mains-powered applications.The IC includes various protection features such as thermal shutdown, auto-restart for over-temperature and output short-circuit conditions, and line undervoltage lockout to ensure safe and reliable operation. The LNK304GN-TL is compliant with international safety standards, including UL, CQC, and BIS, making it suitable for use in applications requiring regulatory approval.
