DC DC Switching Controllers Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure compatibility with your PCB footprint for the QFN-28 package. Check for moisture sensitivity levels and reflow soldering profiles prior to assembly. Confirm availability status as distribution channels may vary.

DC DC Switching Controllers Selection Notes

Select this component when a single-output synchronous boost solution is required with inputs up to 60 V. Consider the thermal performance of the QFN-28 package for your specific power dissipation needs. Evaluate the need for low IQ during standby modes versus peak load efficiency requirements.

DC DC Switching Controllers Part Context

This part belongs to the LTC7893 family of synchronous boost controllers. It is distinct from buck or buck-boost variants like the LTC7878 or LTC7813. The #PBF suffix indicates lead-free packaging compliant with RoHS standards, while the UFDM designation specifies the QFN-28 body style.

DC DC Switching Controllers Replacement Considerations

Direct substitutes are not explicitly listed in the provided data. Review the broader LTC7893 family for pin-compatible alternatives if different packaging options are needed. Verify electrical parameters against similar Analog Devices boost controllers before substitution.
