Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DER-G corresponds to the 6-USPC package and 3MHz frequency variant. Confirm the output voltage setting matches the required 2.9V application parameter. Ensure compatibility with the intended thermal management solution for the small footprint.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a low input voltage start-up capability below 1V is required alongside moderate output current needs. The 3MHz switching frequency allows for smaller external inductors compared to lower frequency alternatives. Verify that the fixed 2.9V output meets the system voltage requirements without additional adjustment circuitry.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9141 series of synchronous step-up converters from Torex Semiconductor. The series is characterized by its ability to operate from very low input voltages, making it suitable for single-cell battery applications. The E-series typically denotes specific output voltage and package combinations within the broader product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

XC9141E23DER-G offers a similar form factor but provides a fixed 2.3V output instead of 2.9V. XC9141B29DER-G shares the 2.9V output specification but utilizes a different SOT-25-5 package, requiring PCB layout adjustments.
