Procurement Notes

Verify the specific suffix and package variant against the official datasheet to ensure compatibility with design requirements. Confirm that the component meets all relevant RoHS standards and environmental specifications prior to integration. Cross-reference the manufacturer's latest documentation to validate pinout assignments and thermal performance characteristics for the MSOP-EP package.

Selection Notes

Select this controller when designing circuits that require handling input voltages up to 100 V while maintaining precise current mode regulation. The device is suitable for applications needing flexible topology options such as SEPIC or flyback. Ensure the external components support the desired switching frequency range and that the thermal pad connection is properly managed for heat dissipation in the target enclosure.

Part Context

This component belongs to the LT3758 family of wide input range controllers manufactured by Analog Devices. It shares architectural similarities with other devices in the series but is distinguished by its specific package configuration and operational parameters. The IMSE#PBF designation indicates the industrial temperature grade and lead-free packaging compliant with standard manufacturing protocols.

Replacement Considerations

Direct substitutes include LT3758AIMSE#PBF and LT3758HMSE#PBF, which offer extended temperature ranges. Verify thermal ratings and electrical specifications before swapping between these variants to ensure system reliability under varying environmental conditions.
