Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix KD1R against official datasheets to confirm the 2.75V fixed output and 3MHz frequency parameters. Ensure compatibility with the LGA-8B01-8 footprint during procurement. Confirm RoHS compliance status through manufacturer documentation before ordering.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.75V output is required from a 5.5V maximum input source. The 3MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the 1.5A load requirement fits within the thermal constraints of the LGA-8B01-8 package.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9289 series of HiSAT-COT synchronous buck converters. The series is characterized by high integration and low standby current, designed for space-constrained applications. The B2KD1R suffix specifically denotes the fixed output voltage and switching frequency configuration within this family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Cross-reference with other XC9289 variants sharing the same LGA-8B01-8 package if pinout compatibility is critical. Verify that substitute parts support the same 2.75V output and 3MHz switching frequency to maintain circuit performance without redesign.
