The Torex XC9140C502MR-G is a synchronous boost DC-DC converter that provides a fixed 5V output from an input voltage between 0.9V and 5.5V. With a maximum output current of 100mA, it is well-suited for powering USB OTG devices, 5V logic circuits, and portable audio equipment. The device comes in a compact SC-74A (SOT-753) package, enabling space-efficient designs. Its high-efficiency synchronous architecture helps extend battery life in portable applications.
- Fixed 5V Output: Ideal for USB and standard 5V logic rails, eliminating the need for external feedback resistors.
- Low 0.9V Startup: Can operate from nearly depleted batteries, maximizing energy extraction.
- Synchronous Rectification: Improves efficiency compared to asynchronous designs, reducing heat and extending battery life.
- Small Footprint: SC-74A/SOT-753 package fits into compact consumer and industrial designs.
USB On-the-Go (OTG) Power
When a portable device needs to provide 5V to a USB peripheral, this boost converter can generate the required 5V rail from a 3.7V Li-ion battery, enabling OTG functionality in smartphones and tablets.
5V Logic and Sensor Supply
Many industrial sensors and logic ICs require a 5V supply. The XC9140C502MR-G can step up from a lower battery voltage to provide a stable 5V rail in remote monitoring equipment.
Battery-Powered Audio Amplifiers
For portable speakers or headphone amplifiers, a regulated 5V supply ensures consistent audio output power and reduces distortion as the battery discharges.
Arduino and Maker Projects
In battery-powered Arduino projects, this converter can boost a 2xAA battery pack (2.4V-3.0V) to 5V, allowing the use of standard 5V shields and sensors.
Portable Chargers (Power Banks)
As a secondary boost stage, it can provide a clean 5V output for charging small devices from a single-cell battery, with the 100mA limit suitable for low-power wearables.
Automotive Sensor Interfaces
In automotive environments where the battery voltage can drop during cranking, the wide input range ensures a stable 5V output for sensors and CAN transceivers.
