Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DMR' against the official Torex datasheet to confirm the package type and tape-and-reel specifications. Ensure the fixed output voltage matches the design requirements, as this variant does not support external resistor adjustment. Cross-reference the RoHS compliance status with the manufacturer's latest documentation before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.1V output is required from a 2V to 6V input source. The 3MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the SOT-25-5 package constraints for PCB layout. This part is suitable for applications prioritizing moderate current delivery with minimal external circuitry complexity.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the XC9235 series of synchronous rectification type DC/DC converters. The series integrates built-in driver transistors to minimize external component count. The XC9235C designation typically indicates a fixed output voltage variant within the A/B/C/E/G family, distinguished by its specific voltage setting and packaging configuration.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for XC9235C31DER-G if a USP-C-EP-6 package is preferred instead of SOT-25-5. Verify XC9235A31DMR-G only if the input voltage range or internal transistor characteristics differ significantly in the specific application context.
