Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance and halogen-free status according to manufacturer documentation. Confirm the package type USP-C-EP-6 matches your PCB footprint requirements. Ensure input voltage does not exceed 5.5 V to prevent device damage. Cross-reference the datasheet for exact pinout definitions before finalizing assembly.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.5 V output is required from a 2.5 V to 5.5 V source. The 3 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 1.5 A current limit for load requirements. The USP-C-EP-6 package suits space-constrained designs. Verify thermal performance under maximum load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9288 series of HiSAT-COT synchronous buck converters. The series offers various fixed output voltages while maintaining consistent electrical characteristics like 3 MHz switching frequency and low quiescent current. The XC9288B15DER-G specifically targets applications requiring a stable 1.5 V rail.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Other XC9288 variants with different output voltages (e.g., XC9288B10DER-G for 1.0 V) share identical pinouts and functionality. Direct substitutes must match the 1.5 V output specification. Verify compatibility with existing inductor and capacitor selections due to the fixed 3 MHz frequency.
