Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix ECER against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with your PCB footprint, as the USP-C-EP-6 package requires precise soldering techniques. Cross-reference the part number with authorized distributors to confirm current availability status and regional distribution restrictions before finalizing procurement plans.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.45 V output is required from inputs between 2.5 V and 5.5 V. It is suitable for designs prioritizing high efficiency at light loads due to its PFM capability. Consider the 1.5 A current limit and 1.2 MHz frequency when sizing external inductors and capacitors. Verify thermal performance requirements given the compact USP-C-EP-6 package and operating temperature range.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9288 series of HiSAT-COT synchronous buck converters. The series is characterized by high integration and stability. Other variants in the family offer different fixed output voltages, such as 1.55 V or 1.65 V, while maintaining similar electrical characteristics and packaging options for design flexibility.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other XC9288 series parts with identical output voltages, such as XC9288B1FCER-G (1.55 V) if voltage tolerance allows adjustment. Check XC9287B1ECER-G for similar performance but note it lacks PFM auto-control. Always verify pinout and thermal pad configurations match the existing design layout.
