The Torex XC9140C392MR-G is a high-efficiency synchronous Boost DC-DC converter IC designed to deliver a fixed 3.9V output from a wide input voltage range of 0.9V to 5.5V. Capable of supplying up to 100mA, this converter is ideal for battery-powered and low-power applications. Its compact SC-74A/SOT-753 package makes it suitable for space-constrained designs. The device ensures stable performance across varying load conditions, making it a reliable choice for portable electronics, IoT devices, and other applications requiring a boosted voltage rail.

  • Wide Input Voltage Range (0.9V to 5.5V): Enables operation from a single-cell battery down to 0.9V, maximizing battery utilization.
  • Fixed 3.9V Output: Provides a stable, regulated voltage rail without the need for external resistor dividers, simplifying design.
  • High Efficiency Synchronous Boost: Internal synchronous rectification improves efficiency, extending battery life in portable devices.
  • Compact Package (SC-74A/SOT-753): Saves valuable PCB space, ideal for miniaturized electronic products.

Battery-Powered IoT Sensors

With a minimum input voltage of 0.9V, this boost converter can operate from a single alkaline or NiMH cell, efficiently stepping up to 3.9V to power sensors, microcontrollers, and wireless transceivers in IoT nodes.

Wearable Electronics

The compact SC-74A/SOT-753 package and low 100mA output capability make it ideal for space-constrained wearables like smart watches and fitness bands, where a stable 3.9V rail is needed from a small Li-ion or coin cell battery.

Portable Medical Devices

Devices such as glucose monitors and digital thermometers require reliable low-power operation. The XC9140C392MR-G ensures a consistent 3.9V supply even as the battery voltage drops, extending device runtime.

Remote Controls and Key Fobs

These battery-operated devices benefit from the converter's ability to boost a nearly depleted battery (down to 0.9V) to a usable 3.9V, ensuring consistent RF transmission power and reliable operation.

Energy Harvesting Systems

In systems powered by small solar cells or thermoelectric generators, the low 0.9V start-up voltage allows the converter to efficiently boost low, variable input voltages to a stable 3.9V for storage or direct use.
