Innoscience Technology will demonstrate industry-leadership at the upcoming IEEE Applied Power Electronics Conference and Exposition (APEC) 2024.
At the industrial session, Innoscience will address the exponential demand in power by datacenters due to the processing power necessitated by Artificial Intelligence (AI) applications. The paper will show that with Innoscience’s 650V InnoGaN, it is possible to make a 2kW AC/DC conversion PSU with a high power density and a peak efficiency above 96%, thereby meeting the recent stringent 80 Plus titanium efficiency rating.
Thanks to the absence of a body diode on GaN devices, a simple Totem pole PFC architecture can be implemented while still reaching high levels of efficiency. At the booth Innoscience will also showcase a 4.2kW AC/DC conversion PSU meeting 80 Plus titanium efficiency rating within a power density of 130W/in3.
Moreover, to address the 48V to 12V DC-DC power conversion inside the data center, Innoscience will present an all GaN HEMTs based 1kW 48V-12V unregulated LLC solution that features GaN power devices both at the primary side (100V devices) as well as at the secondary side (40V devices). In order to maximize the power density and simplify the circuit, the solution uses Innoscience’s recent integrated SolidGaN solution (ISG3201), which integrates an half-bridge (made by two 100V/3.2mOhm InnoGaN devices) with its driver, protection etc.. in one package. The final all GaN 1kW 48V-12 converter has a size of only 50mmx30mmx9mm, which is 70% smaller than a Silicon counterpart rated only 600W. The converter achieves a peak efficiency of 98.5%.
Dr. Denis Marcon, General Manager Innoscience Europe, comments: “Reliability is also an important consideration for data centers, because they operate 24/7 and they must guarantee continuity of service. Therefore, in this paper we will also present strong reliability data of Innoscience’s HV and LV GaN power devices, including end-of-life testing for life-time calculation which shows reliability data at the parts-per-billion level.”
Yi Sun, General Manager Innoscience America comments: “Innoscience today has one of the widest portfolio of GaN power device solutions covering 30V to 700V applications, a family of GaN discrete available in standard packages (e.g. QFN, FCQFN, TO252 etc..) as well as integrated GaN IC solutions that include in one chip the GaN FET, the driver, protections etc.”
Visitors to the Innoscience booth at APEC will also see new products, such as the NV100FQ030A, a 100V bidirectional IC that can be employed to deliver high efficiency in applications including battery management systems, high-side load switching in bidirectional converters, and various switching circuits in power systems.
Yi Sun, adds: “Innoscience is leading the GaN industry with many new products that are industry firsts. That is why our devices are finding applications in all markets, from consumer chargers through industrial and communications and into the automotive sector. Join us at booth 1543 to find out more.”

Texas Instruments introduced two new power conversion device portfolios to help engineers achieve more power in smaller spaces, providing the highest power density at a lower cost. TI’s new 100V integrated gallium nitride (GaN) power stages feature thermally enhanced dual-side cooled package technology to simplify thermal designs and achieve the highest power density in mid-voltage applications at more than 1.5kW/in3.
TI’s new 1.5W isolated DC/DC modules with integrated transformers are the industry’s smallest and most power-dense, helping engineers shrink the isolated bias power-supply size in automotive and industrial systems by over 89%. Devices from both portfolios will be on display at this year’s Applied Power Electronics Conference (APEC), Feb. 25-29 in Long Beach, California.
“For power-supply designers, delivering more power in limited spaces will always be a critical design challenge,” said Kannan Soundarapandian, general manager of High Voltage Power at TI. “Take data centers, for example – if engineers can design power-dense server power-supply solutions, data centers can operate more efficiently to meet growing processing needs while also minimizing their environmental footprint. We’re excited to continue to push the limits of power management by offering innovations that help engineers deliver the highest power density, efficiency and thermal performance.”
Increase power density and efficiency with 100V integrated GaN power stages
With TI’s new 100V GaN power stages, LMG2100R044 and LMG3100R017, designers can reduce power-supply solution size for mid-voltage applications by more than 40% and achieve industry-leading power density of over 1.5kW/in3, enabled by GaN technology’s higher switching frequencies. The new portfolio also reduces switching power losses by 50% compared to silicon-based solutions, while achieving 98% or higher system efficiency given the lower output capacitance and lower gate-drive losses. In a solar inverter system, for example, higher density and efficiency enables the same panel to store and produce more power while decreasing the size of the overall microinverter system.A key enabler of the thermal performance in the 100V GaN portfolio is TI’s thermally enhanced dual-side cooled package. This technology enables more efficient heat removal from both sides of the device and offers improved thermal resistance compared to competing integrated GaN devices.

Shrink bias power supplies by more than 89%
With over eight times higher power density than discrete solutions and three times higher power density than competing modules, TI’s new 1.5W isolated DC/DC modules deliver the highest output power and isolation capability (3kV) for automotive and industrial systems in a 4mm-by-5mm very thin small outline no-lead (VSON) package. With TI’s UCC33420-Q1 and UCC33420, designers can also easily meet stringent electromagnetic interference (EMI) requirements, such as Comité International Spécial des Perturbations Radioélectriques (CISPR) 32 and 25, with fewer components and a simple filter design.The new modules use TI’s next-generation integrated transformer technology, which eliminates the need for an external transformer in a bias supply design. The technology allows engineers to shrink solution size by more than 89% and reduce height by up to 75%, while cutting bill of materials by half compared to discrete solutions.
With the first automotive-qualified solution in this small package, designers can now reduce the footprint, weight and height of their bias supply solution for electric vehicle systems such as battery management systems. For space-constrained industrial power delivery in data centers, the new module enables designers to minimize printed circuit board area.
