Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DMR-G' against the official Torex Semiconductor datasheet to confirm the exact output voltage, package type, and tape-and-reel quantity. Ensure that the required output voltage matches the fixed 4.8V specification provided in the part number. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance status and availability of the specific reel packaging before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 4.8V output is required from a single-cell lithium-ion or lithium-polymer battery source. The high 0.8A output current capability makes it suitable for powering RF modules or displays. Consider the 3MHz switching frequency for smaller passive component sizes compared to lower-frequency alternatives. Verify that the load current does not exceed the rated 0.8A limit under all operating conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This model belongs to the XC9142 series of synchronous step-up DC/DC converters from Torex Semiconductor. The series is characterized by high efficiency and compact footprint options. The XC9142E48DMR-G specifically denotes the variant with a 4.8V fixed output and SOT-25-5 surface-mount packaging. It complements other variants in the family that offer different fixed output voltages and package styles.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes within the same series include XC9142E45DMR-G (4.5V) and XC9142E50DMR-G (5.0V), provided the system design can tolerate the voltage difference. Other packages such as WLP-6 may be considered if board space allows, though pin compatibility must be verified. Generic replacements require matching input/output voltage ranges, current ratings, and switching frequencies.
