AC DC Converters, Offline Switchers Procurement Notes

This component is officially marked as No Longer Manufactured by NXP Semiconductors. Verify availability through authorized distributors or secondary market suppliers. Confirm RoHS3 compliance status if required for specific regulatory standards. Check for alternative packages such as the /518 variant if pin compatibility allows. Ensure final units are new original stock from reputable sources.

AC DC Converters, Offline Switchers Selection Notes

Select this part only for legacy designs requiring the specific STARplug™ architecture. Consider the 650V breakdown voltage for appropriate line voltage applications. Evaluate the 10kHz to 200kHz frequency range against EMI requirements. Since the part is obsolete, assess long-term supply chain risks before finalizing the design.

AC DC Converters, Offline Switchers Part Context

The TEA1520T belongs to NXP's STARplug™ series of SMPS controllers for low-power systems. It is an integrated offline switcher combining control logic with a power MOSFET. The product line includes variants like TEA1520T/N2,112 and TEA1520T/N2,518. All listed variants share similar functional characteristics but may differ in packaging or minor specifications.

AC DC Converters, Offline Switchers Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. As the TEA1520T/N2,118 is discontinued, engineers must evaluate newer generations of STARplug™ devices or other compatible flyback controllers that meet the 650V and 30W requirements.
