LNK563PN

LNK563PN Description

The LNK563PN is a high-performance offline switcher IC designed for flyback topology applications, manufactured by Power Integrations. This device is part of the Power Management (PMIC) category and is housed in a through-hole package, specifically an 8DIP tube. The LNK563PN offers a breakdown voltage of 700V, ensuring robustness in high-voltage applications. It features an internal switch, which simplifies the design process and reduces the component count. With a maximum power output of 2.5 watts, it is suitable for low-power applications requiring high efficiency and reliability.

The LNK563PN operates at a switching frequency of 83kHz, which allows for the use of smaller, more cost-effective magnetics while maintaining high efficiency. The device includes comprehensive fault protection mechanisms such as current limiting, open-loop protection, over-temperature protection, and short-circuit protection, ensuring safe operation under various conditions. The duty cycle is rated at 70%, providing a balance between efficiency and power delivery.

The LNK563PN is REACH unaffected and RoHS compliant, making it suitable for environmentally conscious designs. It also has a moisture sensitivity level (MSL) of 1, indicating unlimited storage time without the need for special handling, which is beneficial for long-term inventory management.
