XC9301A303MR-G

DC DC Switching Controllers Overview

The XC9301A303MR-G is a step-up and step-down DC-DC controller manufactured by Torex Semiconductor. It operates at a switching frequency of 300kHz, enabling efficient voltage regulation for buck-boost applications. The component is designed to manage power conversion by stepping voltage either up or down as required by the circuit topology. This specific model variant is packaged in a reel format for surface-mount assembly.

DC DC Switching Controllers Feature Summary

• Supports both step-up and step-down voltage conversion modes
• Operates with a fixed 300kHz switching frequency
• Functions as a dedicated DC-DC controller IC

DC DC Switching Controllers Applications

• Buck-boost DC-DC power supply circuits
• Voltage regulation systems requiring bidirectional step-up/step-down capability
• Embedded power management modules

DC DC Switching Controllers Procurement Notes

Verify the exact part number XC9301A303MR-G against official Terox Semiconductor documentation to ensure compatibility. Confirm that the reel packaging matches your production requirements. Cross-reference the datasheet specifications for any specific ordering suffixes or variants to avoid procurement errors.

DC DC Switching Controllers Selection Notes

Select this controller when a fixed 300kHz operation is suitable for the design. Ensure the application requires a buck-boost topology rather than simple buck or boost configurations. Verify that the external component selection aligns with the controller's control loop requirements for stable voltage regulation.

DC DC Switching Controllers Part Context

This component belongs to the XC9301 series of DC-DC controllers from Torex Semiconductor. The series includes various models differentiated by switching frequencies and internal parameters. The XC9301A303MR-G specifically denotes the 300kHz variant within this family, sharing common controller architecture with other members.

DC DC Switching Controllers Replacement Considerations
