Procurement Notes

Verify the specific suffix '1,118' against the manufacturer's official documentation to confirm tape and reel packaging specifications. Ensure that the ordering part number matches the exact variant required for your design, as minor suffix differences can indicate variations in packaging or testing criteria. Cross-reference with the latest datasheet revision to confirm compliance with current regulatory standards.

Selection Notes

Select this component for designs requiring a compact solution with minimal external components. It is suitable for applications where high power factor and low harmonic distortion are critical. Consider the thermal performance of the integrated switch when determining heatsinking requirements. Evaluate the fixed frequency operation against system noise sensitivity constraints.

Part Context

This part belongs to NXP's GreenChip family of PFC controllers. It is designed to replace discrete solutions by integrating the control logic and power stage into a single package. This integration simplifies PCB layout and reduces overall system size compared to traditional two-stage approaches.

Replacement Considerations

Consult NXP's official substitution guide for direct pin-compatible alternatives. Verify that any substitute maintains the same voltage rating and current handling capabilities. Ensure that the replacement part supports the same control topology to avoid redesigning the feedback loop.
