DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-N 16-pin tube packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified 11.1 V operating voltage and 2.5 A drive requirements for optimal circuit performance.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring high-frequency operation and active clamp regulation. Consider the 16-pin SOIC-N package for surface-mount assembly constraints. Evaluate thermal management needs given the +105°C maximum operating temperature rating and ensure input voltage ranges align with the controller's operational limits.

DC DC Switching Controllers Part Context

This part belongs to the UCC289x series of current-mode active clamp controllers from Texas Instruments.
