Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific package type USP-C-EP-6 against your PCB footprint requirements. Confirm the fixed 1.65 V output voltage matches your system design needs. Check RoHS compliance documentation for regulatory adherence. Ensure thermal management strategies align with the SMD/SMT installation style and operating temperature range specifications provided in the datasheet.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.65 V output is required from a 2.5 V to 5.5 V input source. The 1.5 A current capability suits moderate load applications. Consider the USP-C-EP-6 package for space-constrained designs. The 1.2 MHz frequency allows for smaller passive components compared to lower-frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9288 series of HiSAT-COT synchronous buck converters. It shares core architectural features with other variants in the family, such as the XC9288B11CPR-G and XC9288B13CPR-G, differing primarily in output voltage settings and package options like SOT-89-5 or USP-C-EP-6.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include XC9288B11CPR-G (1.1 V output) and XC9288B13CPR-G (1.3 V output) if voltage adjustments are acceptable. Verify package compatibility when replacing with USP-C-EP-6 variants like XC9288B1HCER-G.
