DC DC Switching Controllers Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and electrical characteristics, as variations exist within the XC9220 family. Ensure compatibility with external MOSFETs or integrated switch requirements specified in the datasheet. Confirm RoHS compliance status through the manufacturer's latest certification records before finalizing procurement specifications.

DC DC Switching Controllers Selection Notes

Select this model when a 500 kHz switching frequency and 3 A current capability are required. The USP-6C package suits applications needing a small footprint. Verify that the input voltage range up to 30 V aligns with the system design. Compare against other XC9220 variants if different frequencies or packages are preferred for thermal or layout constraints.

DC DC Switching Controllers Part Context

This component belongs to the XC9220 series of synchronous step-down DC-DC controllers from Torex Semiconductor. The series is characterized by high efficiency and compact packaging options suitable for modern portable electronics. The XC9220B variant specifically denotes the 500 kHz switching frequency configuration within this product line.

DC DC Switching Controllers Replacement Considerations

XC9220B09AMR-G shares identical electrical specifications but uses an SOT-25-5 package instead of USP-6C. Other XC9220B variants may differ in switching frequency or package type. Verify pin-to-pin compatibility and thermal performance before substituting.
