The LYT2003D-TL from Power Integrations (LYTSwitch™-2 series) is an isolated Flyback offline switcher with an integrated 725V switch. It delivers up to 7 W at 85kHz switching frequency with a 55% maximum duty cycle. Housed in a 7-lead 8-SOIC package, it operates across a -40°C to 150°C junction temperature range, making it well suited to compact isolated power supplies.
- Integrated 725V switch reduces external component count and simplifies isolated Flyback designs.
- Isolated topology provides galvanic isolation for safety-critical applications.
- 85kHz switching and 55% max duty cycle support compact, efficient 7 W supplies.
- Wide -40°C to 150°C junction range enables use in demanding thermal environments.
- Compact 8-SOIC package saves board space.
