XC9301A252MR-G

DC DC Switching Controllers Overview

The XC9301A252MR-G is a step-up and step-down DC-DC controller IC manufactured by Torex Semiconductor. It operates at a fixed switching frequency of 180 kHz and supports both buck and boost topologies within a single device. The component utilizes an SOT-25-5 surface-mount package for compact integration. Designed for efficient power management, it regulates output voltage through external components controlled by the internal driver circuitry.

DC DC Switching Controllers Feature Summary

• Integrates buck and boost control capabilities in a single chip
• Operates at a fixed 180 kHz switching frequency
• Utilizes a compact SOT-25-5 surface-mount package

DC DC Switching Controllers Applications

• Battery-powered portable devices requiring variable input voltages
• Systems needing both step-up and step-down regulation from a single source
• Compact consumer electronics with limited board space

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 your PCB footprint for the SOT-25-5 form factor. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components. Confirm that the 180 kHz frequency aligns with your electromagnetic interference requirements.

DC DC Switching Controllers Selection Notes

Select this controller when a design requires both step-up and step-down functionality without using multiple discrete regulators. The fixed 180 kHz frequency simplifies filter component selection compared to adjustable frequency controllers. Consider the SOT-25-5 package size constraints during layout planning. Verify that external inductor and capacitor values meet the stability requirements defined in the official datasheet.
