Procurement Notes

Verify the specific suffix 'AUTT2U' against official ABLIC documentation to confirm tape and reel packaging details. Ensure compatibility with standard SOT-23-5 footprints during PCB layout. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing procurement orders.

Selection Notes

Select this component when a fixed 6.0V output is required from a 2.5V to 16V input source. The 1A current capability suits moderate load applications. Consider the 180kHz switching frequency for balancing component size and efficiency. Verify thermal performance requirements for the SOT-23-5 package under expected load conditions.

Part Context

This part belongs to the S-8521 series of synchronous buck regulators from ABLIC. The series is designed for applications requiring high efficiency and compact solutions. The S-8521B variant typically denotes specific output voltage and package configurations within the broader product family.

Replacement Considerations

Check for direct pin-compatible alternatives in the S-8521 series with different output voltages if system requirements change. Verify electrical parameter overlaps with other manufacturers' synchronous buck converters offering similar 1A output and 16V input ratings.
