Electrical Engineer

The introduction of the InnoMux-2 family of integrated circuits (ICs) by Power Integrations represents a significant advancement in power conversion technology. By integrating both AC-DC and DC-DC conversion stages into a single chip, these ICs address a common challenge in power supply design: the efficiency loss due to multiple conversion stages. Traditionally, each stage of conversion incurs a loss of energy, typically as heat, which not only affects the system's performance but also contributes to increased operational costs and environmental impact.

The use of 750 V PowiGaN gallium-nitride transistors is a key factor in the reduction of power losses. Gallium nitride (GaN) is known for its high electron mobility and thermal conductivity, which allows for faster switching and less heat generation compared to silicon-based transistors. This results in higher efficiency and the potential for downsizing the power supply components. Moreover, the zero-voltage switching technique reduces switching losses, contributing to the overall efficiency of the system.

The potential impact on businesses, particularly those manufacturing white goods, industrial systems and displays, is substantial. The reduction in component count and printed circuit board (PCB) footprint not only simplifies the manufacturing process but also reduces material costs. Additionally, the increased efficiency and compliance with the European Union's energy-using product (EuP) regulations for standby usage make these ICs an attractive option for companies looking to enhance the energy efficiency of their products and reduce their ecological footprint.

Market Analyst

From a market perspective, Power Integrations' launch of the InnoMux-2 ICs could potentially disrupt the power supply component market by setting a new standard for energy efficiency and integration. The company's pricing strategy, starting at $1.11 for 50,000-unit quantities, positions the product competitively, which may influence the pricing dynamics within the industry and impact the market share of existing power supply ICs.

The high efficiency and reduced component count provided by InnoMux-2 ICs are not only in line with the increasing demand for energy-efficient and compact electronic devices but also offer manufacturers the ability to streamline their supply chains. This could lead to a reallocation of market share among suppliers, with Power Integrations poised to capture a larger segment if the product is adopted widely.

Investors and stakeholders should monitor the adoption rate of InnoMux-2 ICs and any resulting shifts in customer preference. Companies that quickly integrate these ICs into their products may gain a competitive advantage in terms of cost savings and regulatory compliance, which could translate into improved financial performance and stock valuation.

Environmental Analyst

From an environmental standpoint, the InnoMux-2 ICs contribute to the global effort to reduce energy consumption and greenhouse gas emissions. The energy efficiency gains, achieving system efficiency above 90 percent, are significant when considering the scale at which these ICs could be deployed in consumer and industrial electronics. This efficiency leap aligns with broader sustainability trends and regulatory pressures, such as the European Union's directives on energy consumption.

By enabling products to meet stringent energy regulations, Power Integrations is not only providing a technical solution but also supporting the corporate social responsibility objectives of its clients. The reduction in no-load consumption to less than 30 mW is particularly noteworthy, as it demonstrates the company's commitment to addressing the often-overlooked issue of standby power draw, which can accumulate to substantial energy usage at scale.

Environmental considerations are increasingly influencing business decisions and consumer behavior and Power Integrations' focus on energy-efficient technologies could enhance its brand reputation and customer loyalty, ultimately impacting its financial success and investor sentiment.

New GaN-based ICs combine AC-DC and DC-DC stages into a single power converter; cut power system losses by up to 50 percent

LONG BEACH, Calif.--(BUSINESS WIRE)-- APEC 2024 – Power Integrations (NASDAQ: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today 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.
