Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance and lead-free status as per manufacturer standards. Confirm the USP-C-EP-6 package dimensions match your PCB footprint requirements. Ensure the fixed 3.55 V output aligns with your system design, as this variant does not support adjustable output voltages. Cross-reference the datasheet for thermal dissipation guidelines in your specific enclosure environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 3.55 V output is required from a 2.5 V to 5.5 V input source. The 1.5 A output current capability suits moderate load applications. Consider the 1.2 MHz switching frequency for balancing component size and efficiency. The USP-C-EP-6 package is suitable for space-constrained designs requiring surface mount installation.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9288 series of HiSAT-COT synchronous buck converters. The series is characterized by high efficiency and compact external component requirements. The XC9288A3FCER-G specifically denotes the 3.55 V fixed output version within this family, sharing core architecture with other variants differing only in output voltage settings.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations
