The Torex XC9140C452MR-G is a synchronous step-up DC-DC converter designed to deliver a fixed 4.5V output from a low-voltage input source. Operating from 0.9V to 5.5V, it efficiently boosts battery voltage for portable and low-power applications. The device supports up to 100mA output current and is housed in a compact SC-74A (SOT-753) package, making it suitable for space-constrained designs. Typical applications include battery-powered devices, wearables, and sensor systems.
- Low Start-Up Voltage: Operates from inputs as low as 0.9V, enabling use with single-cell batteries.
- High Efficiency: Synchronous rectification improves efficiency, extending battery life in portable devices.
- Compact Package: SC-74A/SOT-753 footprint saves PCB space for miniaturized designs.
- Fixed Output: 4.5V regulated output simplifies design and reduces external component count.
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 4.5V 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 XC9140C452MR-G ensures a consistent 4.5V output even as the battery discharges, maintaining measurement accuracy and device reliability.
Wearable Electronics
Space-constrained wearables benefit from the compact SC-74A package. The low quiescent current and high efficiency at light loads make it ideal for continuous operation in smartwatches and fitness trackers.
Remote Controls and Key Fobs
These devices often use two AAA batteries. The boost converter maintains a stable 4.5V output for IR LEDs or RF transmitters, ensuring consistent signal strength and range regardless of battery state.
LED Bias Supplies
For small LCD backlights or indicator LEDs, the 4.5V fixed output can directly drive LED strings with a simple resistor. The boost topology allows operation from a lower voltage source, simplifying power supply design.
