Würth Elektronik developed flyback transformers for the switching regulators:
LT3573EMSE#PBF, LT3574EMS#PBF, LT3575EFE#PBF and LT3748
More than 60 different transformers are available in stock. The demo boards impress with their simple design and the need for less components around the IC, as usual. Aging of the typical optocoupler used in isolated flyback converter designs are past now, as these switching regulators work with a primary side sensing, instead of using an optocoupler.
Würth Elektronik offers a wide variety of demo kits, which each includes a demo board. This board can be adjusted to input and output requirements by changing only two resistors and the transformer. Therefore, it’s an easy and fast customized isolated switch mode power supply.
