Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact part number XC9141D34CMR-G against official Torex Semiconductor documentation to ensure compatibility with your design requirements. Confirm that the 3.4V fixed output and 500mA current rating align with your load specifications. Check for RoHS compliance status if required by your manufacturing standards. Ensure the SOT-25-5 package footprint matches your PCB layout constraints before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.4V output is required from a low-voltage input source up to 6V. The 1.2MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 500mA output limit for load requirements. The synchronous topology is suitable for applications prioritizing efficiency over cost-sensitive non-synchronous designs.

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 offers various fixed output voltages and switching frequencies.
