Technology & Innovation
Torex stands out for its proprietary Ultra-Small Package (USP) technology, which enables the creation of energy-efficient, high-performance analog power ICs in minimal footprints. This is especially critical in space-constrained environments such as wearables, IoT sensors, and electric vehicles. The company's innovations focus on ultra-low power consumption and fast switching speeds—attributes vital to energy-sensitive applications.
One shining example is the XCL108 Series, a step-up DC/DC converter featuring a built-in inductor and an exceptionally low supply current of 400nA. This makes it ideal for medical devices, wireless sensors, and portable electronics where long battery life and compact design are essential. Additionally, Torex's work on wireless charging and energy harvesting—through collaborations with Matrix Industries and NGK Insulators—emphasizes integration of perovskite solar cells and EnerCera® batteries for efficient, self-powered modules. These breakthroughs are supported by Torex’s vertically integrated production through Phenitec, allowing in-house semiconductor manufacturing and accelerated innovation cycles.
