Procurement Notes
Verify current product status as the AOZ1017DI series may be classified as obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors only. Ensure the specific suffix matches required packaging and pinout specifications. Cross-reference datasheet revisions to guarantee compatibility with existing circuit designs before procurement.
Selection Notes
Select this component for applications requiring a 3A current capacity with a 500kHz switching frequency. It is suitable for designs needing an input range up to 16V without synchronous rectification benefits. Consider thermal performance in the 8-VDFN package when determining heat dissipation requirements. Verify that the adjustable output range meets the target load voltage needs.
Part Context
This part belongs to the EZBuck family of regulators from Alpha & Omega Semiconductor. These devices are designed for simplicity and high efficiency in compact form factors. The AOZ1017DI specifically targets cost-sensitive applications where non-synchronous operation is acceptable. It complements other parts in the series offering different current ratings and package options.
Replacement Considerations
Check for direct substitutes within the same EZBuck family such as the AOZ1017AI if available. Evaluate alternative 3A buck regulators from other manufacturers ensuring matching input/output ranges and package dimensions. Verify pin compatibility and control interface similarities to minimize redesign efforts during replacement.
