AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix QDR-2Q1 against official Texas Instruments documentation to confirm automotive qualification status and pinout compatibility. Ensure the source document explicitly lists this part number as active or available, as lifecycle status changes frequently. Cross-reference the SOIC-8 package dimensions with your PCB footprint requirements before finalizing procurement decisions.

AC DC Converters, Offline Switchers Selection Notes

Select this component when designing automotive power stages requiring current-mode control with high efficiency. The 1 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the 50% maximum duty cycle meets the voltage conversion ratio requirements of the target Boost, Flyback, or Forward topology application.

AC DC Converters, Offline Switchers Part Context

This part belongs to the UCC2813 series of low-power BiCMOS controllers. It is distinct from non-automotive variants like the UCC2813N-2 by its extended temperature range and qualification standards. The 'Q1' suffix indicates automotive grade, while 'DR' specifies the tape-and-reel packaging format suitable for automated assembly processes.

AC DC Converters, Offline Switchers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Texas Instruments directly for qualified replacements or verify if the standard UCC2813 series meets the specific automotive environmental requirements.
