The LNK6665K-TL is a high-performance Power Management Integrated Circuit (PMIC) that operates as an AC/DC converter and an offline switcher. It is capable of providing a regulated output voltage with up to five times the output current of the traditional linear regulator. The LNK6665K-TL incorporates advanced features such as a pulse-width modulation (PWM) control scheme and an active clamping technique, as well as a variety of protection features to ensure system safety. The LNK6665K-TL is designed to fulfill the requirements of many off-line digital and power supplies and is ideal for applications such as LCD TVS, digital audio players, and Blu-ray, DVD and digital set-top boxes.

The LNK6665K-TL has a primary control loop architecture that consists of a fixed frequencycurrent mode control, an active clamp network and an Under Voltage Lockout (UVLO) circuit. The active clamp network is used as a modified Boost converter, which clamps the oscillator reference voltage to lower voltage levels, thus resulting in a quasi-constant switching frequency over a wide range of input voltages. The UVLO circuit ensures that the output of the converter is only enabled once the input voltage is below its turn-on threshold. The fixed frequency current mode control optimizes the output ripple and overshoot performance, while maintaining excellent load and line regulation.

The LNK6665K-TL has an internal power transistor design which allows for high efficiency, low losses and improved thermal performance. The circuit features a 50 Hz ( nominal ) transient response time, as well as a power on reset (POR) feature that helps to prevent accidental startup in case of over-voltage or over-current conditions. The circuit also features cycle-by-cycle current limiting and thermal protection that helps to protect the circuit from damage due to over-current or over-temperature conditions. The LNK6665K-TL also has an optional output voltage synchronization feature that allows for synchronizing the output voltage to an external clock to further reduce the output ripple for applications that require low output ripple.

The LNK6665K-TL is an ideal choice for AC/DC power applications, in particular those requiring high power and efficiency. Its wide range of features and excellent performance make it an ideal choice for a variety of high power, low voltage applications such as LCD TVs, digital audio players and Blu-ray, DVD and digital set-top boxes. The LNK6665K-TL can be used with a wide range of input voltages and output current levels, making it suitable for a variety of applications that require high performance and reliability.
