Power Integrations LinkSwitch™-3 LNK6427K is an offline, high-frequency, quasi-resonant flyback converter IC. Designed for efficient power conversion, this component integrates a high-voltage power MOSFET and a controller into a single 12-ESOP package. It supports switching frequencies up to 85kHz, enabling compact transformer and output capacitor designs. The LNK6427K features robust fault protection, including current limiting, open-loop, over-temperature, and short-circuit protection. With a 725V breakdown voltage and an isolated output topology, it is suitable for a variety of AC-DC power supply applications. This device is commonly utilized in consumer electronics, industrial automation, and lighting control systems.
