LNK364GN-TL Integrated Circuits (ICs)

The LNK364GN-TL is a 660V integrated high voltage offline switch from Power Integrations. The device integrates all of the components required for an offline switch into a single package, including a 700V SenseFET and a 780V half-bridge rectifier. In addition, the device has a high-voltage integrated low-side gate driver and thermal protection system. This makes the LNK364GN-TL suitable for a wide range of offline power supplies and motor drive applications, including power supplies for motor drives, home appliances and industrial automation equipment.The LNK364GN-TL is an integrated high voltage offline switch that operates by clamping the peak voltage to the reference voltage. This ensures that the AC line voltage is regulated, even if the electrical load or the AC line voltage fluctuates. The switch operates in both continuous and discontinuous current modes, enabling it to be used in a wide range of applications. The device features a soft-start current limit, allowing it to start up gradually and reduce the inrush current when the device is switched on. In addition, the device has integrated thermal protection and fault detection, providing reliable operation and robust protection against overload, short circuit and other fault conditions.The LNK364GN-TL utilizes a single-ended primary-inductor converter (SEPIC) topology to deliver a regulated output voltage. The SEPIC topology is a type of AC-DC conversion. It operates by rectifying the AC input voltage to generate a DC voltage, and then using an inductor to create a regulated output voltage. The device also has a hysteretic current control (HCC) loop, which minimizes the effects of AC line ripple and minimizes power losses.In addition, the LNK364GN-TL has a transient overvoltage protection circuit, which monitors the output voltage of the device and quickly shuts off the power supply if the output voltage exceeds a predetermined threshold. This feature helps protect the device and any other components connected to it from damage caused by transient overvoltages.Finally, the device incorporates an exposed pad for enhanced thermal performance. The exposed pad provides an additional thermal path for heat generated by the device, helping to increase its efficiency and thermal performance.Overall, the LNK364GN-TL is a highly integrated, high voltage offline switch, suitable for a wide range of power supply and motor drive applications. The device features integrated thermal protection, fault detection, and transient overvoltage protection, providing reliable operation and robust protection against overload and short circuit conditions. Furthermore, the device has a single-ended primary-inductor topology, allowing it to produce a regulated output voltage. The device also has an exposed pad for enhanced thermal performance, helping to increase its efficiency and thermal performance.
