Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout compatibility and temperature grade. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference datasheet revisions to validate electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring two isolated or non-isolated outputs from a single high-voltage rail. Evaluate the thermal performance requirements based on the total load current and ambient conditions. Confirm that the external inductor selection aligns with the desired ripple current and saturation limits specified in the technical data.

Part Context

This part belongs to the LT8616 family of dual synchronous buck converters designed for high-density power applications.
