POWER INTEGRATIONS LAUNCHES 1700 V GAN SWITCHER IC, SETTING NEW BENCHMARK FOR GALLIUM NITRIDE TECHNOLOGY
1700 V GaN InnoMux-2 IC delivers efficiency of better than 90 percent from a 1000 VDC bus, supplying up to 70 W from three accurately regulated outputs
Power Integrations (NASDAQ: POWI ), the leader in high-voltage integrated circuits for energy-efficient power conversion, today introduced a new member of its InnoMux™-2 family of single-stage, independently regulated multi-output offline power supply ICs. The new device features the industry’s first 1700 V gallium nitride switch, fabricated using the company’s proprietary PowiGaN™ technology. The 1700 V rating further advances the state-of-the-art for GaN power devices, previously set by Power Integrations’ own 900 V and 1250 V devices, both launched in 2023. The 1700 V InnoMux-2 IC easily supports 1000 VDC nominal input voltage in a flyback configuration and achieves over 90 percent efficiency in applications requiring one, two or three supply voltages. Each output is regulated within one percent accuracy, eliminating post regulators and further improving system efficiency by approximately ten percent. The new device replaces expensive silicon carbide (SiC) transistors in power supply applications such as automotive chargers, solar inverters, three-phase meters and a wide variety of industrial power systems.
Radu Barsan, vice president of technology at Power Integrations, said, “Our rapid pace of GaN development has delivered three world-first voltage ratings in a span of less than two years: 900 V, 1250 V and now 1700 V. Our new InnoMux-2 ICs combine 1700 V GaN and three other recent innovations: independent, accurate, multi-output regulation; FluxLink™, our secondary-side regulation (SSR) digital isolation communications technology; and zero voltage switching (ZVS) without an active-clamp, which all but eliminates switching losses.”
“1700 V rating is substantially higher than any other commercially available GaN HEMT that we are aware of,” said Ezgi Dogmus, activity manager, compound semiconductors at Yole Group. “The Power GaN device market is poised to reach $2 billion by decade's end, expanding across various application spaces with potentially attractive cost advantages over SiC.” (1)

SEOUL, South Korea (AP) — North Korea on Tuesday fired multiple short-range ballistic missiles toward its eastern sea, the South Korean military said, as the country continued its weapons demonstrations hours before the U.S. presidential election.
South Korea’s Joint Chiefs of Staff said the missiles flew about 400 kilometers (250 miles) but didn’t specify how many were fired. Japanese Prime Minister Shigeru Ishiba said they landed in waters outside of Japan’s exclusive economic zone and there were no immediate reports of damage.
The launches came days after North Korean leader Kim Jong Un supervised a flight test of the country’s newest intercontinental ballistic missile designed to reach the U.S. mainland. In response to that launch, the United States flew a long-range B-1B bomber in a trilateral drill with South Korea and Japan on Sunday in a show of force. That drew condemnation from Kim’s powerful sister, who on Tuesday accused North Korea’s rivals of raising tensions with “aggressive and adventuristic military threats.”
South Korean officials have said that North Korea was likely to dial up its military displays around the U.S. presidential election to command the attention of Washington. South Korea’s military intelligence agency said last week that North Korea has also likely completed preparations for its seventh nuclear test.
Outside officials and analysts say North Korea eventually hopes to use an expanded nuclear arsenal as leverage to win concessions such as sanctions relief after a new U.S. president is elected.
There are widespread views that Kim Jong Un would prefer a win by Republican candidate Donald Trump, with whom he engaged in high-stakes nuclear diplomacy in 2018-19, seeing him as a more likely counterpart to give him what he wants than Democratic candidate Kamala Harris. During campaigning, Harris said she won’t “cozy up to tyrants and dictators like Kim Jong Un who are rooting for Trump.”
North Korea claimed last week that the Hwasong-19 it tested on Oct. 31 was “the world’s strongest” ICBM, but experts say the solid-fuel missile was too big to be useful in war. Experts say North Korea has yet to acquire some critical technologies to build a functioning ICBM, such as ensuring that the warhead survives the harsh conditions of atmospheric re-entry.
Tensions between the Koreas are at their highest point in years as Kim has repeatedly flaunted his expanding nuclear weapon and missile programs, while reportedly providing Russia with munitions and troops to support President Vladimir Putin’s war in Ukraine.
On Monday, U.S. State Department spokesperson Matthew Miller told reporters that as many as 10,000 North Korean soldiers were in Russia’s Kursk region near Ukraine’s border and were preparing to join Moscow’s fight against Ukraine in the coming days. If they engage in combat, it would be North Korea’s first participation in a large-scale conflict since the end of the 1950-53 Korean War.
After a meeting in Seoul on Monday, senior South Korean and European Union officials expressed concerns about Russia’s possible transfer of technology to North Korea to enhance its nuclear program in exchange for its troops. Such transfers would “jeopardize the international non-proliferation efforts and threaten peace and stability on the Korean Peninsula and across the globe,” they said.
In response to North Korea’s growing nuclear threat, South Korea, the United States and Japan have been expanding their combined military exercises and updating their nuclear deterrence plans built around U.S. strategic assets.
North Korea has portrayed the joint military drills by its rivals as rehearsals for an invasion and used them to justify its relentless pursuit of nuclear weapons and missiles.
At a U.N. Security Council meeting Monday, North Korea’s ambassador, Kim Song, defended the North's nuclear and ICBM programs as essential for the country’s self-defense and a necessary response to what it perceives as nuclear threats from the United States. He stressed that North Korea would accelerate the build-up of “our nuclear force that can counter any threat presented by hostile nuclear weapon states.”
U.S. Deputy Ambassador Robert Wood warned that the U.S. cannot stand back from North Korea’s expanding nuclear program and the growing threat to U.S. security “without a response.”
Wood also repeated last week’s call for Russia to say whether there are North Korean troops on the ground in Russia. “We’re not in a court here,” Russian Deputy Ambassador Anna Evstigneeva replied, “and the questions of the United States, in the spirit of an interrogation, is not something I intend to answer.”
