The LNK6407D-TL from Power Integrations is a Flyback offline switcher in the LinkSwitch™-3 series, delivering up to 7.5 W with a 725V integrated switch. It provides galvanically isolated output, up to 85kHz switching frequency, and 55% maximum duty cycle in a compact 8-SOIC (7-lead) package. Current limiting, open-loop, over-temperature, and short-circuit protection support dependable low-power isolated AC-DC designs across -40°C to 150°C junction temperatures.
- Integrated 725V switch reduces external component count and board space.
- Flyback topology with isolated output suits supplies up to 7.5 W.
- Comprehensive protection (current limiting, open loop, over temperature, short circuit) improves reliability.
- Wide -40°C to 150°C junction temperature range.
- Compact 8-SOIC 7-lead package for space-constrained designs.
Compact Isolated Adapters
The LNK6407D-TL's integrated 725V switch and Flyback topology suit small isolated AC-DC adapters up to 7.5 W with minimal external components.
Auxiliary & Bias Supplies
