Power Integrations LinkSwitch™-HP LNK6669K is an advanced offline flyback switcher IC designed for high-performance power supply applications. This 12-ESOP packaged component operates within a switching frequency range of 120kHz to 136kHz, providing efficient power conversion up to 77W. Key features include integrated 650V breakdown voltage, extensive fault protection including current limiting, overload, over-temperature, over-voltage, and short-circuit protection, and a maximum duty cycle of 64%. The LNK6669K is suitable for isolated output topologies and features internal switching capabilities. Its robust design and comprehensive protection mechanisms make it ideal for use in consumer electronics, industrial control systems, and medical equipment. The device is supplied in a 12-ESOP package for surface mounting and operates across a wide temperature range of -40°C to 150°C (TJ).
