AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix (e.g., TL) against the datasheet to confirm reel packaging and moisture sensitivity class. Ensure the design accounts for the specified operating temperature limits and thermal dissipation requirements inherent to the eSOP-12B-5 package. Confirm RoHS compliance status through official manufacturer documentation prior to integration.

AC DC Converters, Offline Switchers Selection Notes

Select this component for low-power offline applications requiring simplified design due to integrated PSR. The 85 kHz frequency allows for smaller magnetics compared to higher-frequency alternatives. Consider the eSOP-12B-5 package for surface-mount assembly needs. Evaluate thermal performance based on the 150°C maximum junction temperature rating.

AC DC Converters, Offline Switchers Part Context

This part belongs to the LinkSwitch-3 family from Power Integrations, targeting cost-sensitive, high-volume consumer and industrial power supplies. It represents a generation of ICs that combine power switching and control to reduce external component count. The series is distinct from the LinkSwitch-HP family, which targets higher power levels up to 90 W.

AC DC Converters, Offline Switchers Replacement Considerations

Consult official substitution guides for direct pin-compatible alternatives within the same family. Verify electrical parameters and thermal characteristics when considering cross-family replacements.
