XC9302A493MR-G

DC DC Switching Controllers Overview

The XC9302A493MR-G is a step-up and step-down DC/DC controller manufactured by Torex Semiconductor. It operates at a switching frequency of 300 kHz and supports an input voltage range of 2 V to 10 V. The device provides a positive output in a buck-boost configuration. It is housed in an SOT-25-5 package with five pins. This component functions as a switching controller for power management applications requiring flexible voltage conversion capabilities.

DC DC Switching Controllers Feature Summary

• Supports both step-up and step-down voltage conversion topologies
• Operates with a fixed switching frequency of 300 kHz
• Provides positive output regulation within the specified input range

DC DC Switching Controllers Applications

• Battery-powered portable devices requiring variable input voltages
• Systems utilizing single-cell lithium-ion batteries with varying charge states
• Applications needing stable output from fluctuating source voltages

DC DC Switching Controllers Procurement Notes

Verify the exact suffix MR-G against the manufacturer's current datasheet to confirm pinout and packaging specifications. Ensure compatibility with external components such as inductors and capacitors, as this is a controller IC rather than a complete converter module. Confirm availability status directly with authorized distributors, as stock levels may vary.

DC DC Switching Controllers Selection Notes

Select this component when a buck-boost topology is required to maintain regulation across an input voltage range that crosses the desired output level. The 300 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the external circuit design can support the controller's drive requirements and thermal constraints.

DC DC Switching Controllers Part Context

This part belongs to the XC9302 series of DC/DC controllers from Torex Semiconductor. The series includes variants with different output voltage settings and package options. The XC9302A493MR-G specifically denotes the 300 kHz frequency variant in an SOT-25-5 package. It is designed for efficient power management in compact electronic systems.

DC DC Switching Controllers Replacement Considerations

Check for XC9302A413MR-G or XC9302A433MR-G if different output voltage configurations are needed within the same family. Ensure any substitute maintains the 300 kHz switching frequency and SOT-25-5 footprint for direct compatibility.
