The LNK6663K-TL is a power management integrated circuit (PMIC). It is part of the AC/DC converters and offline switchers family. It is a member of the LinkSwitch-TN controller family of PMICs, which are designed to increase efficiency and reduce noise caused by AC-DC power conversion and switching regulators.

The LNK6663K-TL features high efficiency and a low no-load standby power dissipation, making it ideal for battery-powered applications. It has a wide input voltage range (90-277Vac) and integrated high voltage EMI filters. It is capable of providing an output voltage of up to 24V, and can deliver an output current of up to 1.4A.

The LNK6663K-TL is designed for applications such as LED lighting and energy-saving lighting systems. It also suits appliances, industrial applications, and other consumer electronics. Its small form factor makes it suitable for space-restricted applications.

The principle of operation of the LNK6663K-TL is essentially the same as that of a conventional buck converter. It is essentially a switched-mode power supply that is used to convert AC voltage from the power line (or power grid) into DC. It works by first quickly switching the AC voltage on and off at a specific frequency. This process creates a “chopped” version of the AC voltage (known as a switched mode voltage), which is then rectified and filtered to create the DC voltage that is required by the end device.

The LNK6663K-TL can be used in multiple topologies including a buck converter, boost converter and a buck-boost converter. It features wide frequency range and a high switching frequency, which allow for better efficiency and faster transient response. The device also provides over-current/short-circuit/over-voltage & over-temperature protection, and is compliant with the latest energy regulation standards.

The LNK6663K-TL is a useful PMIC for AC/DC converters and offline switchers. It has numerous advantages, the most significant being its high efficiency, low standby power dissipation, wide input voltage range, and compact form factor. This makes it an ideal choice for applications such as LED lighting and energy-saving lighting systems.
