LNK6773K

The LNK6773K is a low power offline switcher. It is a polyphase current mode synchronous buck converter specifically designed to operate in the AC input range of 85-265Vac. With a wide input range and low cost, it offers high efficiency, low cost, and low audible noise.

Due to its low power, the LNK6773K is widely used in applications such as home and office appliances, industrial control systems, wireless and broadband audio equipment, consumer electronics and telecom systems.

The LNK6773K is ideal for applications where an AC (mains) input voltage needs to be converted to the DC voltage used by semiconductors and other electrical equipment.

The LNK6773K works by rectifying the AC input voltage and then passing the rectified DC voltage through an inductor. The energy stored in the inductor is used to power the load, while the current in the inductor is controlled by the pulse width modulation (PWM) control circuit. The PWM control circuit modulates the output voltage to achieve the desired duty cycle and thus the output voltage.

The LNK6773K also includes a synchronous rectification circuit to reduce power losses. It also includes protection against over-temperature, short-circuit, output over-voltage and input under-voltage.

The LNK6773K provides a reliable, low-cost solution for offline switching applications. It is designed for use in cost-sensitive applications that require high efficiency and low audible noise. It is suitable for applications where the output voltage is between 8.5V and 48V and the maximum output current is 200mA.

In conclusion, the LNK6773K is a low-cost, high-efficiency, low-noise offline switcher ideal for applications where an AC input voltage needs to be converted to the DC voltage used by semiconductors and other electrical equipment. It is suitable for applications where the output voltage is between 8.5V and 48V and the maximum output current is 200mA.
