Power Integrations announced the InnoMux™-2 family of single-stage, independently regulated multi-output offline power-supply ICs. InnoMux-2 ICs consolidate AC-DC and downstream DC-DC conversion stages into a single chip, providing up to three independently regulated outputs for use in white goods, industrial systems, displays and other applications requiring multiple voltages.
Elimination of separate DC-DC stages slashes component count, reduces PCB footprint and increases efficiency by as much as 10 percentage points compared to traditional two-stage architectures. Efficiency is aided by the ICs’ 750 V PowiGaN™ gallium-nitride transistors, zero-voltage switching (without an active clamp) and synchronous rectification.
Roland Saint-Pierre, vice president of product development at Power Integrations said: “Most modern electronic systems rely on multiple internal voltages to operate various functions such as computing, communication and actuation function – typically heat, light, sound or motion of some kind. But losses in each conversion stage are compounded, degrading system performance and generating heat.
The InnoMux-2 IC overcomes this challenge by providing up to three independently regulated voltage outputs or two voltage output and a constant current output from a single stage, achieving a compact and efficient power sub-system with low component count.”
InnoMux-2 ICs deliver up to 90 watts of output power with accurate regulation of better than ±3 percent across the full input line, load, temperature and differential current step conditions. Total power system efficiency (AC to regulated low-voltage DC segment) is above 90 percent; the advanced InnoMux-2 controller also manages light-load power delivery, avoiding the need for pre-load resistors and reducing no-load consumption to less than 30 mW. This conserves power for necessary functionality in applications subject to the 300 mW allowance for standby usage under the European energy-using product (EuP) regulations.
InnoMux-2 devices leverage Power Integrations’ thermally efficient InSOP™24 and InSOP™28 packages with PCB cooling, so no heatsink is required. Device options include dual- and three-output constant voltage (CV); optionally, one output may be dedicated to constant current (CC) drive, suitable for powering LEDs in displays or for high-speed charging of an internal battery. Typical applications include TVs, monitors, appliances, networking, home and building automation, LED emergency lighting and industrial power supplies.

Infineon Technologies AG introduced the 750V G1 discrete CoolSiC™ MOSFET to meet the increasing demand for higher efficiency and power density in industrial and automotive power applications. The product family includes both industrial-graded and automotive-graded SiC MOSFETs that are optimized for totem-pole PFC, T-type, LLC/CLLC, dual active bridge (DAB), HERIC, buck/boost, and phase-shifted full bridge (PSFB) topologies.
The MOSFETs are ideal for use in both typical industrial applications, such as electric vehicle charging, industrial drives, solar and energy storage systems, solid state circuit breaker, UPS systems, servers/ datacenters, telecom, and in the automotive sector, such as onboard chargers (OBC), DC-DC converters, and many more.
The CoolSiC MOSFET 750 V G1 technology features excellent RDS (on) x Q fr and superior RDS (on) x Q oss Figure-of-Merits (FOMs), resulting in ultra-high efficiency in hard-switching and soft-switching topologies respectively. Its unique combination of high threshold voltage (V GS(th), Typ. of 4.3 V) with low Q GD/Q GS ratio ensures high robustness against parasitic turn-on and enables unipolar gate driving, leading to increased power density and low cost of the systems.
All devices use Infineon’s proprietary die-attach technology which delivers outstanding thermal impedance for equivalent die sizes. The highly reliable gate oxide design combined with Infineon’s qualification standards delivers robust and long-term performance.
With a granular portfolio ranging from 8 to 140 mΩ RDS (on) at 25°C, this new CoolSiC MOSFET 750 V G1 product family meets a wide range of needs. Its design ensures lower conduction and switching losses, boosting overall system efficiency.
Its innovative packages minimize thermal resistance, facilitate improved heat dissipation, and optimize in-circuit power loop inductance, thereby resulting in high power density and reduced system costs. It’s important to note that this product family features the cutting-edge QDPAK top-side cooled package.

GlobalWafers held its board meeting to approve 2023 financial results.
FY2023 consolidated revenue reached NT$70.7 billion with YoY 0.5%; gross profit of NT$26.4 billion, with -12.9% YoY, gross profit margin of 37.4%, with -5.8% YoY; operating income of NT$20.1 billion, with -19.7% YoY, operating income margin of 28.4%, with -7.1% YoY; profit before tax of NT$26.5 billion, with 31.8% YoY, profit before tax margin of 37.5%, with 8.9% YoY; net profit of NT$19.8 billion, with 28.6% YoY, net profit margin of 28.0%, with 6.1% YoY; EPS reached NT$45.41, with an increase of more than NT$10 compared with the previous year.
FY2023 consolidated revenue grew in 3 concessive years and rose to the highest again! FY2023 EPS, profit before tax margin and net profit margin all hit record high.
Despite the semiconductor industry in 2023 facing a slowdown in global economic and consumer electronics demand, coupled with increased inventory pressure, GlobalWafers benefited from a high proportion of LTAs and maintained high utilization rates for FZ wafers and compound semiconductor wafers, achieving continued growth in revenue throughout the year.
Looking ahead to 2024, as terminal market inventories are gradually reabsorbed, AI features will progressively integrate into personal computers, tablets, and smartphones, potentially driving a wave of upgrades. In the meantime, the AI ecosystem relies on supports from peripherals and semiconductor components, fueling demands for edge computing, high-performance computing (HPC) and spurring the development of low-power consumption-related components (SiC, ULLD, IGBT…).
More innovations are expected to be introduced, such as 5G, electrification, smart cockpits, and autonomous driving, contributing to the growth momentum in the semiconductor market. Besides, policies related to energy transition and net-zero carbon emissions in various countries have laid a long-term foundation for the development of compound semiconductors. In 2024, the market is expected to gradually recover, with memory leading the way in releasing signals.
However, the pace and extent of economic recovery depend on various factors, including different terminal applications and global economic uncertainties such as war, rising shipping costs, interest rate changes, and exchange rate fluctuations. Positioned in the upstream of the semiconductor industry, GlobalWafers anticipates a recovery a quarter or two later than downstream and expects a healthier performance in the second half of the year compared to the first half, considering that customers will prioritize depleting existing inventories.
With a comprehensive product spectrum ranging from 3” to 12” semiconductor wafers, GlobalWafers is able to cater for customers’ needs to cope with market fluctuations of individual products. Moreover, the Company has carried out expansion plans to get ready for the acceleration toward advanced processes.
GlobalWafers has become a long-term partner of customers with its focus on sustainability and the unique advantages of highly regionalized deployment that allows the Company to supply products in proximity, reducing the carbon footprint and the impact of carbon tariffs, while also mitigating geopolitical risks. With flexible asset allocation and a sound financial structure, GlobalWafers is resilient to market volatility and continues to create profits through prudent operations.
