The Power Integrations LNK6418E is an isolated Flyback offline switcher from the LinkSwitch™-3 series with an integrated power switch. It delivers up to 10 W with a 725V breakdown rating, up to 85kHz switching frequency, and 55% maximum duty cycle. Comprehensive fault protection includes current limiting, open loop, over temperature, and short circuit safeguards. Housed in a 7-SSIP package with exposed pad, it operates across a -40°C to 150°C junction temperature range.
- Integrated power switch reduces external component count and simplifies Flyback design.
- 725V breakdown voltage provides headroom for universal offline AC input.
- Up to 10 W output with up to 85kHz switching supports compact isolated supplies.
- Comprehensive fault protection (current limiting, open loop, over temperature, short circuit) enhances reliability.
- Wide -40°C to 150°C junction temperature range suits demanding thermal environments.
Compact AC-DC Adapters
The LNK6418E integrates the power switch and controller in a Flyback topology, delivering up to 10 W for space-constrained chargers and adapters. The 725V breakdown rating provides margin for universal AC input.
Standby & Auxiliary Supplies
With up to 85kHz switching and 55% max duty cycle, this isolated Flyback switcher suits auxiliary bias supplies requiring galvanic isolation and reliable regulation.
