The LNK6664K-TL is an Integrated Gate-Driver and Power MOSFET used for controlling buck or boost converters. It is a power management IC (PMIC) that falls under the categories of AC DC converters and offline switchers. It contains an integrated gate driver and 6 NMOS power switching elements for various applications such as DC-DC converters and portable electronics.The LNK6664K-TL minimizes power-loss from heat and eliminates the need of large spreaders and thermal protection implemented by external circuit. It offers low switching loss and low on-resistance. It operates in PWM mode with a frequency range of up to 190 kHz, while supplying up to 12 A.The LNK6664K-TL is suitable for portable power applications such as notebook computers, gaming consoles, LCD monitors, and other mobile applications. This device is also available in a tiny WLCSP package which is ideal for use in space-limited applications.The LNK6664K-TL works on the principle of Pulse-Width Modulation (PWM). PWM is a technique used to control the average power delivered to the load. It achieves this by rapidly switching the power ON and OFF, with the varying ON/OFF time determined by the input PWM signal. It is mainly used to regulate the output voltage or current of a power supply, although it may also be used for major power control applications.The LNK6664K-TL is equipped with three integrated high-speed power DMOS drivers, providing very low switching loss and improved EMI performance when compared with traditional devices. The integrated input PWM control allows the user to set and control voltage and current up to different levels. The output power can be managed by the internal current and temperature sensors.The LNK6664K-TL also contains an internal soft start circuit that prevents inrush current at start-up and thermal shutdown function to protect against component defects. The device has a 5V standby voltage input and PWM control up to 7.2V, while the adjustable voltage range is from 0% to 100%.The device is designed to improve the switch\'s performance, making it more ideal for use in AC/DC converters, motor control, and portable electronics. In addition, the LNK6664K-TL is also suitable for high frequency applications, providing higher efficiency and reduced component size due to its high switching frequency up to 190kHz.Power management for various AC/DC and DC/DC applications requires efficient, reliable, and cost-effective switching techniques. The LNK6664K-TL from Linear Technology, a leader in power management solutions, provides just that - efficient and reliable power switching, without compromising quality or performance, at a very affordable price.The advantages of the LNK6664K-TL are numerous. First and foremost, it has a small size - 1.9mm ×1.6mm(WLCSP)- making it ideal for applications with limited space. It also comes with an integrated soft start circuit that eliminates inrush current at the switch’s start-up and a thermal shutdown circuit for added protection against component defects. Furthermore, it is equipped with an input PWM control and an adjustable voltage range of up to 100%.The LNK6664K-TL is a versatile and cost-effective PMIC solution that is suitable for various AC/DC, DC/DC applications, and other mobile applications such as notebook computers, gaming consoles, LCD monitors, and other portable electronics. It offers a wide range of features, such as low switching loss, low on-resistance, and an integrated gate driver, making it a great choice for managing power efficiently in space-limited applications.
