Switching Converter, SMPS Transformers Procurement Notes

Verify that the target design utilizes the specified Linear Technology LT3798 or LT3799 chipset, as this transformer is optimized for these controllers. Confirm that the application requires the specific 2mH inductance value and 4500Vrms isolation rating. Ensure the PCB layout supports the through-hole package dimensions of 15.00mm x 15.75mm. Cross-reference the datasheet for thermal performance under expected load conditions.

Switching Converter, SMPS Transformers Selection Notes

Select this component when designing flyback converters based on the LT3798/99 architecture. It is suitable for applications demanding high input voltage ranges and robust isolation standards. Consider the physical size constraints and through-hole assembly requirements. This part is intended for offline power conversion rather than low-voltage auxiliary supplies.

Switching Converter, SMPS Transformers Part Context

This component belongs to the Würth Elektronik WE-UNIT series, specifically tailored for mid-power offline applications. It serves as a critical magnetic element in switch-mode power supply designs, ensuring efficient energy transfer and electrical isolation between primary and secondary sides.

Switching Converter, SMPS Transformers Replacement Considerations

Direct substitutes are limited due to the specific tuning for LT3798/99 chipsets. Verify any alternative transformer against the required 2mH inductance, 4500Vrms isolation, and pinout compatibility. Generic flyback transformers may not provide the same performance characteristics for these specific controllers.
