Switching Converter, SMPS Transformers Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct packaging configuration, as variations exist for tape and reel or cut tape formats. Confirm that the requested quantity aligns with standard manufacturing pack sizes to avoid unnecessary handling fees. Ensure the application environment remains within the specified operating temperature limits of -40°C to 125°C for reliable performance. Cross-reference the latest datasheet revision to confirm any recent marking or packaging label changes documented in product change notices.

Switching Converter, SMPS Transformers Selection Notes

Select this transformer when designing flyback converters using compatible controller ICs such as the LT3573, LT3574, LT3575, or LT3748 series from Linear Technology. The 25µH inductance value suits specific power transfer requirements around 9.6W. Ensure the PCB layout accommodates the 13.34mm x 15.24mm footprint and allows for adequate clearance given the 11.56mm maximum height. Verify that the input voltage range of 18 to 30V matches the system design constraints.
