The LNK306GN-TL is an offline switcher which belongs to the family of PMIC– AC DC converters. It is mainly used for driving resistive and capacitive loads in LED lighting and home automation applications. This part requires a low component count, providing very efficient power conversion from AC-DC.

The LNK306GN-TL is optimized for universal input range from 85V to 277VAC, making it a suitable option for cost-sensitive solutions. It offers primary-side feedback control circuitry, resulting in a reliable solution and high efficiency up to 86.5%. The LNK306GN-TL is housed in a very small, 3-pin package, making it suitable for applications where small size and high efficiency are important factors.

This device offers up to 20W of power with an operating temperature range of -40 to 105°C and features an auto restart function in case of fault detections. It also contains short-circuit-protective circuitry, allowing it to automatically reset when a short circuit is detected. Additionally, the LNK306GN-TL is compliant with UL698A, IEC60250, EN55015 and CSA C22.2 standards.

The working principle of the LNK306GN-TL  is as follows. The power line from the AC-DC power source is rectified and utilized as the input voltage. The rectified voltage is then converted to a regulated DC voltage by means of an inductor-capacitor coupled filter. The output filter is then connected with the output load, where it will provide the required power to the load. The output voltage is also monitored by an oscilloscope, which provides feedback to the internal controller for regulating the output voltage.

The LNK306GN-TL has a wide range of applications, such as LED lighting, home automation, and industrial control systems. It is commonly used in the automotive industry to power the ECU (Engine Control Unit) and in residential and commercial illumination systems. In addition, this device is also suitable for driving resistive and capacitive loads in solar powered energy systems.

In summary, the LNK306GN-TL is an offline switcher which belongs to the family of PMIC-AC/DC converters. It offers universal input range, high efficiency up to 86.5%, wide operating temperature range, and up to 20W of power. This device can be used in a variety of applications, such as LED lighting, home automation, and industrial control systems. Additionally, it is compliant with multiple safety standards, making it a suitable choice for cost-sensitive solutions.
