XC9301A542MR-G

DC DC Switching Controllers Overview

The XC9301A542MR-G is a buck-boost DC-DC controller IC manufactured by Torex Semiconductor Ltd. It functions as a step-up and step-down regulator, converting input voltages to stable output levels. The device operates with a switching frequency of 180kHz. It is housed in an SC-74A (SOT-753) package. The component supports input voltage ranges from 2V to 10V. It is designed for power management applications requiring efficient voltage conversion across varying load conditions.

DC DC Switching Controllers Feature Summary

• Integrates buck-boost topology for both step-up and step-down voltage regulation capabilities
• Operates at a fixed switching frequency of 180kHz for consistent performance
• Supports wide input voltage range suitable for diverse power supply scenarios

DC DC Switching Controllers Applications

• Battery-powered portable electronics requiring extended runtime
• Systems with fluctuating input voltage sources needing stable output
• General-purpose power management circuits in consumer devices

DC DC Switching Controllers Procurement Notes

Verify the exact ordering suffix and package marking against official Torex Semiconductor documentation to ensure compatibility. Confirm that the SC-74A (SOT-753) package type matches your PCB footprint requirements. Check for specific RoHS compliance status if required by your manufacturing standards. Ensure the supplier provides genuine components with traceable origin to avoid counterfeit risks.

DC DC Switching Controllers Selection Notes

Select this component when a single regulator must handle both voltage increase and decrease relative to the input source. Consider the 180kHz switching frequency for EMI constraints and filter component sizing. Evaluate the 2V to 10V input range against your system's minimum and maximum supply voltages. Compare efficiency profiles with alternative controllers if low-power standby modes are critical.

DC DC Switching Controllers Part Context

This part belongs to the XC9301 series of DC-DC controllers from Torex Semiconductor. The series focuses on buck-boost architectures for flexible power delivery. Other variants in the family may differ in switching frequency, current handling, or package options. The XC9301A542MR-G specifically denotes the 180kHz version in the SOT-753 package.

DC DC Switching Controllers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Direct replacement requires matching the buck-boost topology, 180kHz frequency, and SOT-753 package dimensions. Verify control loop stability and external component values when substituting with other manufacturers' parts.
