Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DER' against the official Torex Semiconductor datasheet to confirm package type and tape/reel specifications. Ensure the ordering code matches the required output voltage tolerance and thermal performance. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status as indicated in the latest product documentation.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is needed for boosting low input voltages to a stable 3.3 V rail. The 3 MHz switching frequency allows for smaller external inductors and capacitors compared to lower-frequency alternatives. Consider the 800 mA output capability against the peak load requirements of the target application. Evaluate the thermal performance in the WLP-6 package if high ambient temperatures are expected.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the XC9142 series of synchronous step-up converters designed for portable applications. The series emphasizes high efficiency and low standby current. The XC9142D variant specifically denotes the fixed 3.3 V output version. The family is characterized by its ability to operate efficiently even at light loads through adaptive control modes.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for XC9142D33D0R-G if a different packaging option such as WLP-6 without reel specification is acceptable.
