Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DER-G' against the official Torex datasheet to confirm pinout compatibility and thermal pad requirements. Ensure the ordering information matches the exact package type and marking code. Cross-reference the RoHS compliance status and moisture sensitivity level with current manufacturing data sheets before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 4.1V output is required from inputs ranging down to 0.65V. The 500mA output current capability suits moderate load applications. Consider the 6-pin UFDFN package for surface-mount assembly constraints. Verify that the 3MHz switching frequency aligns with electromagnetic interference (EMI) requirements and inductor selection criteria for the target design.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9142 series of synchronous step-up converters from Torex Semiconductor. The series is characterized by high efficiency and low quiescent current, designed for battery-powered portable equipment.
