Power Integrations LinkSwitch™-3 LNK6427D is an 8-SOIC offline flyback converter IC designed for high-efficiency power supply applications. This component integrates a high-voltage MOSFET and a controller, enabling a compact and cost-effective solution. It supports flyback topologies with switching frequencies up to 85kHz, delivering up to 7.5W. Key fault protection features include current limiting, open loop, over temperature, and short circuit protection, ensuring robust operation. The device is surface mountable and operates across a wide temperature range of -40°C to 150°C (TJ). Applications include consumer electronics, adapters, and lighting. The SO-8C package (7 leads) provides isolated output.
