AC DC Converters, Offline Switchers Procurement Notes

Verify the specific procurement status as the UCC3810TD1 is listed as obsolete or discontinued in certain distributor catalogs. Confirm availability through authorized Texas Instruments channels or approved secondary market suppliers. Ensure that the bare die handling requirements are compatible with your manufacturing assembly processes before placing orders.

AC DC Converters, Offline Switchers Selection Notes

Select this component when a bare die solution is required for high-density power management designs. The UCC3810N variant serves as the equivalent packaged alternative for standard PCB mounting. Consider the thermal and mechanical constraints associated with bare die attachment when choosing between the TD1 and N variants.

AC DC Converters, Offline Switchers Part Context

The UCC3810TD1 belongs to the UCC3810 series of switching controllers from Texas Instruments. This series provides synchronous rectification control for efficient power conversion. The TD1 suffix specifically denotes the die form factor, distinguishing it from the standard PDIP-16 packaged version available under the UCC3810N designation.

AC DC Converters, Offline Switchers Replacement Considerations

The UCC3810N is the direct packaged equivalent offering identical electrical functionality in a 16-PDIP housing. Designers requiring surface mount or through-hole PCB integration should transition to the UCC3810N. Verify pinout compatibility if substituting within existing layouts.
