The Torex XC9140C4914R-G is a high-efficiency synchronous boost (step-up) DC-DC converter designed to deliver a fixed 4.9V output from a wide input range of 0.9V to 5.5V. Capable of supplying up to 100mA, it is ideal for battery-powered and low-voltage applications. The device is housed in a compact 6-XDFN exposed pad package, making it suitable for space-constrained designs. Its low start-up voltage enables operation from single-cell batteries, while the synchronous architecture maximizes efficiency across load ranges. Typical applications include portable electronics, wireless modules, and industrial sensors.
- Ultra-Low Start-Up Voltage: Operates from inputs as low as 0.9V, enabling use with single-cell batteries or energy harvesters.
- High Efficiency Synchronous Design: Integrated synchronous rectifier improves efficiency, reducing heat and extending battery life.
- Compact Package: The 6-XDFN exposed pad package minimizes PCB footprint, ideal for miniaturized devices.
- Fixed Output Accuracy: Provides a stable 4.9V output, simplifying design and ensuring consistent performance.
Battery-Powered IoT Sensors
With a 0.9V minimum input, this boost converter can operate from a single alkaline or NiMH cell, providing a regulated 4.9V rail for sensors, MCUs, and wireless transceivers. Its high efficiency extends battery life in always-on monitoring applications.
Portable Medical Devices
Devices like glucose meters and digital thermometers require stable voltage from a small battery. The XC9140C4914R-G ensures a consistent 4.9V output even as the battery discharges, maintaining measurement accuracy.
Wearable Electronics
The compact 6-XDFN package is ideal for space-constrained wearables. The low quiescent current and high efficiency at light loads help maximize runtime in fitness trackers and smartwatches.
Remote Wireless Modules
For LoRa, Zigbee, or BLE modules needing a 4.9V supply, this boost converter can step up from a 2-cell battery pack. The 100mA capability is sufficient for intermittent RF bursts.
Energy Harvesting Systems
In low-voltage energy harvesting (e.g., thermoelectric or photovoltaic), the 0.9V start-up allows operation from very low source voltages, boosting to a usable 4.9V for storage or direct load.
Industrial Sensor Interfaces
When powered from a 3.3V rail, this converter can generate a higher 4.9V bias for analog front-ends or sensor excitation, ensuring proper signal conditioning in industrial monitoring equipment.
