Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance and halogen-free status as per manufacturer standards. Confirm the 6-XDFN package dimensions match your PCB footprint requirements. Ensure input capacitors support the 1.8V to 6V operating range. Check that the thermal pad connection meets your board's thermal management design. Validate the fixed 2.2V output against your load requirements before ordering.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 2.2V output is required without external resistor programming. The 600mA current rating suits moderate load applications. The 1.2MHz frequency allows for smaller passive components compared to lower frequency alternatives. Consider the 1.8V minimum input voltage if using single-cell battery sources. The synchronous topology offers higher efficiency than asynchronous designs at similar current levels.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9235 series of synchronous step-down converters from Torex Semiconductor. The series offers various fixed output voltages and packaging options. The XC9235G variant specifically utilizes the 6-XDFN package. Other models in the family may differ in output voltage, current rating, or switching frequency. The G suffix typically denotes environmental compliance attributes defined by the manufacturer.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other XC9235 variants with identical 2.2V output and 600mA rating, such as XC9235A22C4R-G or XC9235B22C4R-G, provided package compatibility is verified. Cross-referencing pinouts and thermal pad configurations is essential. Alternative manufacturers offering synchronous buck converters with similar electrical specifications may require circuit redesign.
