Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific output voltage configuration matches the design requirement of 1.45 V before integration. Confirm that the USP-C-EP-6 package footprint aligns with the PCB layout. Ensure the input supply remains within the 2.5 V to 5.5 V operational range to maintain specified performance levels.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed low-voltage output is required from a single-cell battery source. The 3 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 15 uA quiescent current for applications prioritizing standby power conservation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9288 series of synchronous step-down DC/DC converters. It shares the HiSAT-COT architecture with other variants in the family but differs in fixed output voltage settings. The 'A' suffix typically denotes specific output voltage codes within the product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check XC9288A0LDER-G for a 1.25 V output option. Verify XC9288B1ADER-G if a different output tolerance or variant is needed. Ensure any substitute maintains the same USP-C-EP-6 package and 1.5 A current capability.
