The Torex XC9140C492MR-G is a synchronous boost 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, this IC is optimized for battery-powered applications where efficiency and small size are critical. The device is available in a compact SC-74A (SOT-753) package, making it suitable for space-limited designs. Typical applications include portable electronics, IoT devices, and battery backup systems.
- Wide Input Voltage Range (0.9V to 5.5V): Supports operation from a single-cell battery down to deep discharge, maximizing usable battery capacity.
- Fixed 4.9V Output: Provides a stable rail for loads that require a precise voltage without external resistor dividers.
- High Efficiency Synchronous Boost: Internal synchronous rectification reduces power loss, improving efficiency in battery-powered designs.
- Compact Package (SC-74A/SOT-753): Saves PCB space, ideal for miniaturized portable and wearable devices.
Battery-Powered Portable Devices
With a low 0.9V minimum input voltage, this boost converter can efficiently step up a single-cell alkaline or NiMH battery to a regulated 4.9V rail, extending the runtime of handheld instruments and remote controls.
IoT Sensor Nodes
For wireless sensors powered by coin cells or small lithium batteries, the XC9140C492MR-G provides a stable 4.9V supply for RF transceivers and microcontrollers, ensuring reliable data transmission even as the battery voltage sags.
Wearable Electronics
The compact SC-74A package and high efficiency make it ideal for space-constrained wearables like smart watches and fitness bands, where a 4.9V rail is needed for LEDs or haptic drivers.
Portable Medical Devices
In battery-operated glucose meters or pulse oximeters, the wide input range and fixed 4.9V output help maintain consistent performance for sensitive analog front-ends and displays.
Backup Power Systems
When used in a small UPS for memory backup, the converter can boost a 3.6V lithium backup cell to 4.9V, keeping SRAM or RTC circuits alive during main power loss.
LED Flash Drivers
The 100mA output capability is suitable for driving a small LED string at 4.9V in camera flashes or indicator lights, with the boost topology ensuring brightness remains constant as the battery discharges.
