Power Integrations LNK6667K from the LinkSwitch™-HP series is an offline switcher IC designed for flyback topologies. This component operates at switching frequencies between 120kHz and 136kHz, delivering up to 59W. It features integrated 650V MOSFETs and includes comprehensive fault protection mechanisms such as current limiting, overload, over-temperature, over-voltage, and short-circuit protection. The LNK6667K is housed in a 12-ESOP (0.350" width) package with 11 leads and an exposed pad for enhanced thermal performance, suitable for surface mounting. Its isolated output and robust design make it a key component in applications requiring efficient and reliable AC-DC conversion, including consumer electronics and industrial power supplies. The device operates within a junction temperature range of -40°C to 150°C.
