Procurement Notes

Verify current availability status as the part may be subject to limited supply or discontinuation. Confirm that the specific suffix matches the required package and environmental compliance specifications. Cross-reference the manufacturer's official documentation for any recent design changes or obsolescence notifications before finalizing procurement plans.

Selection Notes

Select this controller when designing power stages for Intel processors requiring IMVP-6.5 compatibility. Ensure the external inductor and capacitor values align with the 600 kHz switching frequency requirements. Verify that the input voltage source remains within the 2 V to 26 V operational limits and that thermal management accommodates the specified junction temperature range.
