XC9301A532MR-G

DC DC Switching Controllers Overview

The XC9301A532MR-G is a positive output Buck-Boost DC/DC controller IC manufactured by Torex Semiconductor Ltd. It operates with a switching frequency of 180kHz and supports PWM control mode. The device features a maximum duty cycle of 92% and includes an Enable function for power management. It is housed in a SOT-25-5 package and provides a single positive output configuration.

DC DC Switching Controllers Feature Summary

• Buck-Boost topology supporting step-up and step-down voltage conversion
• Fixed 180kHz switching frequency for consistent noise profile
• High maximum duty cycle capability up to 92%
• Integrated Enable pin for system power control

DC DC Switching Controllers Applications

• Battery-powered portable electronics requiring variable input voltages
• Industrial equipment with fluctuating supply rails
• Automotive subsystems needing stable regulation from varying sources
• Consumer devices utilizing single-cell or multi-cell battery configurations

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 the ordering code matches the required temperature range and lead-free status as defined in the manufacturer's datasheet. Cross-reference the part number with authorized distributors to confirm current product status and availability constraints.

DC DC Switching Controllers Selection Notes

Select this component when a Buck-Boost topology is required to handle input voltages both above and below the target output. The fixed 180kHz frequency aids in filter design but limits high-speed transient response compared to higher-frequency alternatives. Consider the 92% duty cycle limit when designing for minimal input-to-output voltage differentials.

DC DC Switching Controllers Part Context

This controller belongs to the XC9301 series, designed for efficient power management in applications where input voltage varies significantly. It complements other Torex regulators like the XC9714 series by offering buck-boost capabilities rather than simple step-down conversion, suitable for dynamic load environments.

DC DC Switching Controllers Replacement Considerations

Direct substitutes are not explicitly confirmed in public data. Evaluate alternative Buck-Boost controllers from Torex or other manufacturers based on matching 180kHz frequency, SOT-25-5 package, and Enable functionality requirements.
