PMIC (Power Management Integrated Circuit) is an important part of a chipset. Its chief purpose is to regulate and control the power in a circuit. PMICs are categorized into AC DC Converters, Offline Switchers, and so forth, depending on the type and amount of output power they can carry. LNK6768V is an AC DC Converter IC from Power Integrations, and it is classified as a PMIC. This IC has various application fields and a unique working principle.

The LNK6768V IC is mainly used in medium to high-power flyback and forward converter AC/DC power supply designs. This IC also integrates an optimized primary-side control system and isolated feedback topology. Its packaged power rating is in the 11-62 W range, with an input voltage range of 90-265 VAC. The device is designed with in built primary angle control architecture; this generates excellent start-up and line transient response. In addition, it expands efficiency and reduces output voltage ripple. The main applications of the LNK6768V IC are for off-line power supplies, especially in energy efficient lighting and low power products.

The main advantage of the LNK6768V IC is its working principle. It uses a patented boundary-mode bi-directional control to automatically adjust the output power and safely switch from converters to standby. This helps reduce power losses and does not require a conventional programmed start-up sequence. In addition, the primary-side control using active voltage positioning and digital PFC, resulting in low THD and high power factor, play an important role in the self-learning process when adjusting the power supply. Furthermore, it has built in short-circuit protection and over-voltage protection.

Overall, the LNK6768V IC is designed to provide maximum efficiency, reliability, and safety in its applications. It is cost competitive and offers many advantages in terms of compactness, small size, and easier system design. This IC offers excellent performance in off-line ACDC power supply designs, as well as providing flexibility in design and performance. It also supports a wide range of input voltages and output powers, making it suitable for a wide range of applications.
