Switching Converter, SMPS Transformers Procurement Notes

Verify the specific datasheet version when sourcing, as design changes may occur. Confirm that the target application strictly utilizes the LT3748 controller, as this component is tailored for that specific integrated circuit. Ensure thermal management aligns with the 125°C maximum operating temperature specification during system integration.

Switching Converter, SMPS Transformers Selection Notes

Select this component when designing flyback converters based on the LT3748 architecture requiring 30 W output capability. Consider the physical footprint constraints due to its SMD form factor. Validate that the required isolation voltage meets or exceeds 1500 Vrms for the intended safety standards. Compare against other WE-FB series variants if different inductance values or power ratings are needed.

Switching Converter, SMPS Transformers Part Context

This part belongs to the Würth Elektronik WE-FB series, which focuses on flyback transformers for switching mode power supplies. The series is characterized by high efficiency and compatibility with popular controller ICs. The 750311599 specifically addresses the needs of designers using Linear Technology's LT3748 chip, providing a complete magnetic solution rather than a generic transformer.

Switching Converter, SMPS Transformers Replacement Considerations

Direct substitutes within the same family include parts like 750311604, which shares similar LT3748 optimization but differs in inductance (8 µH vs 37 µH) and power rating. Cross-referencing with other manufacturers requires careful verification of pinout, inductance, and isolation ratings to ensure functional equivalence.
