Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance as per manufacturer documentation. Confirm the package type matches the design requirements, specifically the 6-UFDFN exposed pad configuration. Ensure the fixed 3.7V output aligns with the target circuit load specifications before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.7V output is required from a variable low-voltage source. The 1.2MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the maximum input voltage does not exceed 6V to ensure safe operation within the specified limits.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9141 series of synchronous step-up converters. The series is designed for applications requiring efficient power management from single-cell lithium-ion or lithium-polymer batteries. The B-series designation typically indicates specific output voltage options within the broader product family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for other XC9141 variants with different output voltages if 3.7V is unsuitable. Verify pin compatibility with alternative manufacturers offering similar synchronous boost regulators in the 6-UFDFN package.
