The LNK6667V is a Power Management Integrated Circuit (PMIC) designed for applications requiring an AC/DC converter, an offline switcher, and an offline flyback power supply. The device has an integrated 650V MOSFET and a low standby power, and is capable of delivering up to 15W of output power, at up to 90VAC. It can also provide up to 4A of current, while maintaining a high efficiency up to 95%.

The device is composed of an ac input, an output bridge rectifier, and a linear regulator. The ac input is protected from overvoltage and undervoltage conditions using an optocoupler, and is protected against undervoltage conditions to ensure reliability. The output bridge rectifier then converts the ac input into a dc output. The linear regulator then steps down the output voltage to the desired level. This circuit is then used as the reference voltage for the entire power supply.

The main feature of the LNK6667V is its offline switcher, which allows the device to operate in a standby mode while providing high efficiency. This technology helps reduce power consumption while maintaining highest levels of efficiency. The device is capable of switching between the standby mode and operating mode in less than 10μs, enabling the device to continuously switch between the two states. Furthermore, the device also has a fast response time, as the switching speed can be as high as 5MHz.

The LNK6667V is also equipped with a built-in flyback power supply, which further enhances the device’s performance and efficiency. This feature helps prevent the device from oscillating between different states due to disturbances in the power supply. The device is designed to operate at operating temperature up to 85°C and can deliver output power in the range of 0.8 to 15W.

In addition to its support for offline switcher and flyback operation, the LNK6667V also supports over-temperature protection, under-voltage lockout, and maximum power limit protection. All of these features help ensure that the device delivers a safe, reliable performance in a variety of applications.

Overall, the LNK6667V is a powerful and versatile PMIC that can be used in a variety of applications requiring AC/DC converters and offline switchers. The device is highly efficient, supports fast response time, and can provide up to 15W of output power while maintaining high efficiency up to 95%. Moreover, the integrated over-temperature protection, under-voltage lockout, and maximum power limit protection help protect the device from any external disturbances, thus providing a safe, reliable performance in all conditions.
