LNK364DN IC OFFLINE SWIT HV 8SOIC

The LNK364DN is a highly integrated and efficient offline switcher IC, expertly designed for a wide range of non-isolated power supply applications. Housed in a compact 8-SOIC package, this integrated circuit from Power Integrations offers a robust and cost-effective solution for creating energy-efficient power supplies. It's an ideal choice for applications ranging from appliance power supplies and LED drivers to standby power supplies for consumer electronics and industrial control systems. At the heart of the LNK364DN lies its innovative LinkSwitch-TN architecture, which integrates a 700V power MOSFET, oscillator, simple on/off control scheme, a high-voltage switched current source, frequency jittering, cycle-by-cycle current limit, and thermal shutdown circuitry onto a single monolithic IC. This high level of integration minimizes the external component count, simplifying the design process and reducing the overall system cost. The LNK364DN excels in delivering exceptional energy efficiency, easily meeting global energy efficiency standards such as Energy Star and ErP directives.

Its no-load power consumption is remarkably low, typically less than 300mW, making it an excellent choice for applications where standby power is a critical concern. The integrated 700V MOSFET provides a high level of voltage withstand capability, enhancing the reliability and robustness of the power supply. The on/off control scheme provides a simple yet effective method for regulating the output voltage. The IC operates by switching the integrated MOSFET on and off, with the duty cycle adjusted to maintain the desired output voltage. This control scheme offers excellent stability and transient response. The frequency jittering feature helps to reduce EMI (electromagnetic interference), simplifying compliance with regulatory requirements.

By spreading the switching frequency over a small range, the peak EMI emissions are reduced, minimizing the need for external filtering components. The cycle-by-cycle current limit provides robust protection against overload and short-circuit conditions. The current limit is precisely controlled, ensuring that the MOSFET operates within its safe operating area. The thermal shutdown circuitry protects the IC from overheating. If the junction temperature exceeds a safe limit, the IC will automatically shut down, preventing damage. The LNK364DN is designed for ease of use.

It requires minimal external components, simplifying the design process and reducing the overall system cost. The 8-SOIC package is compact and easy to solder, making it suitable for both automated and manual assembly. The LNK364DN is a versatile and reliable offline switcher IC that offers a compelling combination of performance, efficiency, and cost-effectiveness. Whether you're designing a power supply for an appliance, an LED driver, or a standby power supply, the LNK364DN is an excellent choice.
