The LYT5225D-TL from Power Integrations is a multi-topology offline switcher in the LYTSwitch-5 series, supporting flyback, step-down (buck), and step-up (boost) configurations. It integrates a 725V power switch and delivers up to 9W at a 132.7kHz switching frequency. Supplied in a 16-SOIC package with 14 leads, it is rated for -40°C to 150°C junction temperatures.
- Supports flyback, buck, and boost topologies for design flexibility.
- Integrated 725V power switch reduces external component count.
- 9W output and 132.7kHz switching enable compact offline designs.
- Isolated flyback capability provides galvanic isolation when required.
- Wide -40°C to 150°C junction temperature range for reliable operation.
