DC DC Switching Controllers Procurement Notes
Verify component authenticity through authorized Renesas or Intersil distributors due to end-of-life status. Confirm RoHS3 compliance and MSL level 3 handling requirements during storage and assembly. Check for specific PCN updates regarding manufacturing site changes or label modifications before integration into production lines.
DC DC Switching Controllers Selection Notes
Select this component for single-phase synchronous buck applications requiring fixed-frequency operation at 200 kHz. Ensure the design accommodates the 14-SOIC package dimensions and thermal constraints. Verify that the input supply voltage remains within the 10.8V to 13.2V operating range for stable performance.
DC DC Switching Controllers Part Context
