Procurement Notes
Verify component authenticity through authorized distributors or official manufacturer channels due to end-of-life status. Confirm RoHS compliance and package integrity upon receipt. Check datasheet revisions for any design-in updates. Ensure storage conditions meet humidity sensitivity requirements before assembly. Validate pinout compatibility with existing PCB layouts.
Selection Notes
Select this component for CCM PFC designs requiring fixed 66 kHz switching frequency. Consider thermal management capabilities given the 976 mW power dissipation rating. Evaluate system efficiency needs against the 75 uA quiescent current specification. Ensure input voltage ranges align with controller operational limits. Verify footprint compatibility with SOIC-8 land pattern.
Part Context
This part is part of Infineon's PFC controller portfolio, specifically utilizing one-cycle control technology. It falls under the broader PMIC classification within power management integrated circuits. The device represents a solution for improving power quality in AC-DC conversion systems while maintaining compact form factors through its surface-mount packaging.
