DC DC Switching Controllers Procurement Notes

Verify the specific suffix MR-G against official Torex documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for SOT-25-5 components. Cross-reference the 180kHz frequency parameter with system noise requirements. Confirm that the 2V to 10V input range aligns with the target application's power source characteristics before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this component when a buck-boost topology is required to maintain output stability during input voltage fluctuations. The 180kHz frequency offers a balance between component size and efficiency. Consider the SOT-25-5 package constraints for space-limited designs. Verify that the external inductor and capacitor selections support the 92% maximum duty cycle limitation under all expected load conditions.

DC DC Switching Controllers Part Context

This part belongs to the XC9301 series, which includes various variants differentiated by switching frequencies and output configurations.
