A HEMT is a type of electronic switch made from layered semiconductor materials that lets electrical signals move much faster and with less loss than ordinary transistors; think of it as a high-speed highway for electrons. It matters to investors because HEMTs enable faster, more efficient wireless, radar, and power electronics products, so companies that design, manufacture, or use them can gain performance advantages, larger markets, and potentially higher profit margins.
psutechnical
A PSU is a company where the government owns a controlling stake and often plays a direct role in its management and strategy. Think of it like a business that operates with public oversight, similar to a town-run utility versus a private neighborhood service. Investors watch PSUs differently because government involvement can affect profits, dividend policies, regulatory treatment and stability, so these stocks may behave more like policy instruments than pure market-driven enterprises.
gallium-nitride (gan)technical
A semiconductor material used to build electronic components that can operate at higher voltages, temperatures and frequencies than traditional silicon; think of it as a sturdier pipe that lets more power flow with less loss. It matters to investors because gallium‑nitride enables smaller, faster, more energy‑efficient power supplies, radio transmitters and LEDs, creating growth opportunities, premium pricing and supply‑chain risks for companies that make or use the technology.
silicon carbide (sic)technical
Silicon carbide (SiC) is a very durable material made from silicon and carbon, often used in high-performance electronics and industrial tools. It matters because it can handle extreme heat and voltage better than regular materials, making devices more efficient and longer-lasting, especially in electric vehicles and power systems.
dcmtechnical
Debt Capital Markets (DCM) is the part of finance where companies and governments raise money by issuing debt such as bonds or large loans, with banks and underwriters arranging the sale to investors. It matters to investors because DCM activity affects interest rates, credit supply and a borrower’s cost of funding—like a marketplace that sets the price and availability of loaned money, influencing debt returns, default risk and overall market liquidity.
op-ampstechnical
An op-amp (operational amplifier) is a tiny electronic building block that boosts and shapes electrical signals in a wide range of devices, from sensors and audio gear to power controls. Think of it as a smart volume control that can precisely magnify, compare or filter signals so a circuit behaves as intended. Investors care because demand, price and supply of these components affect manufacturing costs, product performance and competitive advantage for companies that rely on analog electronics.

Compact, low-profile designs use highly integrated, 1700 V-rated PowiGaN™, single-HEMT ICs to save space, simplify designs, improve reliability and lower BOM count with 88 percent efficiency
TAIPEI, Taiwan--(BUSINESS WIRE)--
COMPUTEX –Power Integrations (NASDAQ: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today introduced two new ultra-slim, compact auxiliary power supply reference designs for 800 VDC AI data centers. The single-output, 15 W design is only 30 mm by 30 mm with a 7 mm profile, while the isolated, six-rail, 35 W design is only 80 mm by 60 mm with an 8 mm profile. Optimized specifically for the NVIDIA Kyber liquid-cooled, blade-rack architecture, these ultra-compact solutions free up approximately 30 percent space on densely packed main power distribution boards (PDBs) with an estimated 30 percent reduction in the BOM count—streamlining design and improving overall reliability. These designs are highly efficient with at least 88 percent efficiency across line and load.
Compact, low-profile designs using 1700 V-rated PowiGaN, single-HEMT ICs save space, boost efficiency, and improve reliability for NVIDIA Kyber 800 VDC AI Data Center.
“As the only company offering single-HEMT 1700 V GaN devices, Power Integrations can design these best-in-class, highly efficient flyback converters with a low BOM count while maintaining wide safety margins on an 800 V bus,” said Jason Yan, Senior Training Manager at Power Integrations. “The only alternative solutions are discrete, costly silicon carbide (SiC) devices which require 30 percent more components and space to operate.”
The newly published design example reports describe 35 W and 15 W flyback auxiliary power supplies for high-voltage AI data center applications. These compact power supply units (PSUs) provide power for internal components such as MCUs, gate drivers, and op-amps, which deliver critical “control and housekeeping” functions to ensure reliability, efficiency and system safety.
Both designs are based on Power Integrations’ InnoMux™-2 ICs with 1700 V PowiGaN gallium-nitride (GaN) technology. The 1700 V-rated InnoMux-2 IC easily supports 1000 VDC nominal input voltage in a flyback configuration and can deliver flat efficiency of 90 percent in discontinuous conduction mode (DCM) while maximizing power delivery.
