At Pico Box, innovation drives every watt we deliver. In our pursuit of smarter, smaller, and more efficient power solutions, we’ve embraced the cutting-edge combination of the Texas Instruments LM5143 dual synchronous buck controller and low power GaN FETs to redefine what’s possible in DC-DC ATX power supply design.
Why GaN? Because Performance Matters
Gallium Nitride (GaN) is rapidly transforming power electronics, and for good reason. Compared to traditional silicon MOSFETs, GaN FETs switch faster, generate less heat, and take up less space. These advantages make GaN the ideal partner for modern controllers like the LM5143, especially in the tight and demanding spaces of compact ATX form factors.
Efficiency That Goes Beyond Expectations
Our GaN-based designs achieve up to 94% efficiency for applications under 75 W and over 95% for higher power demands. This level of performance not only reduces energy waste but also significantly minimizes thermal stress, enabling quieter, fanless operation in many use cases.
Smaller Size, Greater Flexibility
The combination of GaN FETs and the LM5143 allows us to reduce the size of a typical 67-W power adapter by up to 50%. For end users, this means more compact power supplies without compromising functionality or reliability. Whether you’re building a silent PC, a home server, or an embedded system, space is precious — and we give you more of it.
Optimized for Battery and Always-On Applications
With a no-load quiescent current as low as 15 µA, our solutions excel in scenarios where standby power matters. This is especially valuable for battery-powered systems, energy-efficient desktops, and intelligent power backup architectures.
Wide Input Range, Simpler System Design
Pico Box designs support a versatile input voltage range of 12 V to 48 V, enabled by the LM5143’s robust architecture. This flexibility reduces design complexity, supports multiple power sources, and improves system scalability — whether for industrial, automotive, or consumer electronics applications.
Designed for Engineers. Built for the Future.
At Pico Box, we are not just keeping up with the evolution of power electronics — we are helping to lead it. By integrating low power GaN technology with proven platforms like the LM5143, we’re delivering next-generation DC-DC ATX power supplies that are smaller, cooler, and smarter.
Stay tuned for our upcoming product releases and reference designs that showcase how we’re taking ATX power to the next level.
