The Torex XC9140C1814R-G is a synchronous boost DC-DC converter delivering a fixed 1.8V output from a wide input range of 0.9V to 5.5V. Capable of sourcing up to 100mA, it is designed for low-power applications such as microcontrollers, energy harvesting, and portable medical devices. The compact 6-XDFN package with exposed pad enhances thermal performance, making it suitable for space-constrained designs where efficiency and small size are paramount.
- Ultra-Low 0.9V Startup: Enables operation from single-cell batteries or energy harvesters with very low output.
- Fixed 1.8V Output: Directly powers low-voltage logic and MCUs without external dividers.
- High Efficiency: Synchronous boost topology minimizes losses, critical for battery-powered and energy-harvesting applications.
- Thermally Enhanced Package: 6-XDFN with exposed pad improves heat dissipation in compact layouts.
Low-Power Microcontroller Supply
Many modern MCUs operate at 1.8V. This boost converter can step up from a single-cell battery (0.9V-1.5V) to provide a stable 1.8V rail for low-power embedded systems.
Energy Harvesting Systems
In energy harvesting applications using a small solar cell or thermoelectric generator, the low 0.9V startup voltage allows the converter to boost very low harvested voltages to a usable 1.8V for sensors and transceivers.
Portable Medical Monitors
For wearable health monitors that use 1.8V logic, this converter ensures a stable supply from a coin cell, maintaining accurate readings and wireless communication.
Wireless Sensor Nodes
In Zigbee or Bluetooth Low Energy nodes, the 1.8V output can power the digital core while the RF front-end uses a separate supply, optimizing overall power consumption.
Memory Backup Circuits
For SRAM or RTC backup, the converter can boost a small lithium battery to 1.8V, keeping data intact during main power interruptions.
Portable Instrumentation
Handheld multimeters and field instruments often use 1.8V for their display drivers and logic, and this converter provides a reliable supply from a 2-cell battery pack.
