The Power Integrations LNK3316D-TL from the LinkSwitch™-TNZ series is an isolated offline switcher supporting buck, buck-boost, and flyback topologies with an integrated 725V switch, delivering up to 12W. It switches at 66kHz with a 69% maximum duty cycle, starts up at 18V, and includes EN and soft start control plus current limiting, open loop, over temperature, over voltage, and short circuit protection. It is supplied in a 7-lead 8-SOIC package rated for -40°C to 150°C (TJ).
- Multi-topology support (buck, buck-boost, flyback) with an integrated 725V switch adds design flexibility.
- Up to 12W output power with 66kHz switching suits compact low-power supplies.
- EN and soft start control features improve power-up behavior.
- Comprehensive protection (current limiting, open loop, over temperature, over voltage, short circuit) enhances reliability.
- Wide -40°C to 150°C junction temperature range and 7-lead 8-SOIC package.
