Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'CDR-G' against official Torex documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the USP-B-EP-10 package. Cross-reference the fixed 3.1 V output requirement with system design needs before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.1 V output is required from a low-voltage source up to 5.5 V. The integrated 1A transistor supports peak loads, while the 500 mA continuous rating suits moderate current demands. Consider the 1.2 MHz switching frequency for inductor size optimization and the low quiescent current for battery efficiency.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9135 series of synchronous step-up converters from Torex Semiconductor. The series is characterized by built-in driver transistors and load disconnection features. Variants within the series differ primarily by their fixed output voltage settings, such as 3.1 V, 3.5 V, or other specified levels, while sharing similar operational characteristics and packaging.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for direct substitutes within the XC9135 family offering different fixed output voltages if system requirements change. Verify pinout and thermal pad configurations for any cross-series replacements to ensure mechanical and electrical compatibility.
