Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix C7R-G against official Torex documentation to confirm package type and reel specifications. Ensure compatibility with required input/output voltage ranges before integration. Cross-reference RoHS compliance status using the manufacturer's latest certification documents. Confirm availability through authorized distributors as stock levels fluctuate.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.9 V output is required from a 2.3 V to 6 V input source. Consider the 400 mA current limit and 1.2 MHz switching frequency for design constraints. Evaluate the USPN-6 package size against board space limitations. Compare quiescent current requirements against other regulators in the XC9244 series if lower power consumption is critical.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9244 series of synchronous step-down converters from Torex Semiconductor. The series is characterized by high efficiency and low quiescent current, suitable for battery-operated applications. The XC9244A39C7R-G specifically offers a fixed 3.9 V output, distinguishing it from adjustable or other fixed voltage variants within the same family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for XC9244A33C7R-G if a 3.3 V output is needed instead of 3.9 V. Verify pinout and package compatibility (USPN-6) with any alternative regulators. Consult Torex datasheets for direct substitutes within the XC9244 series that match the 400 mA output current requirement.
