Power Integrations LinkSwitch™-3 series LNK6426D is an 8-SOIC offline flyback converter IC. This component integrates a high-voltage MOSFET and control circuitry to enable highly efficient, low-component-count power supplies. It operates at switching frequencies up to 85kHz and provides up to 6.1W output power. Designed for isolated flyback topologies, the LNK6426D features robust fault protection, including current limiting, open loop, over temperature, and short circuit protection. Its surface mount SO-8C package is suitable for demanding applications in consumer electronics, home appliances, and industrial control systems where power efficiency and reliability are critical. The device operates across a wide temperature range of -40°C to 150°C (TJ).
