Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance status according to the manufacturer's official documentation. Confirm that the USP-C-EP-6 package matches the target PCB footprint requirements. Ensure the fixed 1.7 V output aligns precisely with the load specifications, as adjustable variants are not applicable to this part number.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 1.7 V output is required alongside a 1.5 A current capacity. The 3 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 2.5 V minimum input voltage constraint to ensure proper regulation under varying supply conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9287 series, designed for compact power management solutions. It shares architectural similarities with other HiSAT-COT devices but differs in its fixed output voltage setting. The series emphasizes miniaturization and efficiency for mobile applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes must match the 1.7 V output, 1.5 A rating, and USP-C-EP-6 package. Verify pin compatibility and thermal performance characteristics before integration.
