Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DER-G against official Torex documentation to confirm the 6-UFDFN package type and lead-free status. Ensure compatibility with RoHS3 standards if required by your manufacturing process. Cross-reference the part number with authorized distributors to avoid counterfeit components, as minor suffix variations can indicate different packaging or material specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5.3V output is required from a variable or low-input source up to 6V. The 500mA output current capability suits moderate load applications. Consider the 3MHz switching frequency for smaller external passive component sizes compared to lower-frequency alternatives. Verify that the UFDFN package fits the available PCB real estate and thermal requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9142 series of synchronous step-up converters. The series is characterized by high efficiency and low quiescent current. The XC9142D53DER-G specifically denotes the version with a fixed 5.3V output and the DER-G package variant, distinguishing it from other output voltage options within the same family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other XC9142 variants with similar output voltages, such as XC9142D50DER-G (5.0V) or XC9142D55DER-G (5.5V), provided the voltage tolerance allows. Check datasheets for pinout and electrical parameter compatibility before substitution.
