Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'K' against the official Torex datasheet to confirm it denotes the standard 3.75V fixed output variant within the XC9236 series. Ensure the ordering code matches the USP-C-EP-6 package type. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components, as suffixes can indicate tape-and-reel packaging or specific binning not always explicit in generic listings.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.75V output is required from a 2V to 6V input source. It is appropriate for designs prioritizing high switching frequency (3MHz) to minimize passive component size. Consider the 600mA current limit and 21uA quiescent current for battery life calculations. Ensure the application does not require a shutdown pin, as this specific variant lacks that feature according to available specifications.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9235/XC9236/XC9237 series of 600mA synchronous step-down converters. These ICs integrate N-channel and P-channel driver transistors, eliminating the need for external Schottky diodes. The series is designed for portable equipment, offering high efficiency and low standby current across various fixed output voltage options.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes within the same series include XC9236A33DER-G (3.3V) and XC9236B20DER-G (2.0V), provided the output voltage difference is acceptable. Other XC9236 variants with identical packages and current ratings may serve as functional replacements if the specific 3.75V output is not critical.
