Procurement Notes
This component has reached End-of-Life status as of November 6, 2023. Procurement is restricted to remaining stock or obsolete channels. Verify availability through authorized distributors before design finalization. Ensure replacement strategies are implemented due to discontinuation.
Selection Notes
Select this transformer only when designing with SCALE-iDriver ICs requiring a 15V input voltage. Confirm that the 170µH inductance meets circuit requirements at 100kHz. Verify physical footprint compatibility with PCB layout constraints. Consider end-of-life status when planning long-term production runs.
Part Context
Part of the SIT12xxI series, the SIT1217I complements Power Integrations' gate driver ecosystem. It provides isolated power for driving high-voltage switches. The series includes variants for different input voltages, such as the 5V SIT1253I. This specific model targets applications demanding robust isolation and compact packaging.
Replacement Considerations
Public confirmed substitute part numbers are not available. As the product is discontinued, no direct official replacements are listed. Designers must evaluate alternative gate driver solutions or transformers compatible with other driver families.
