Power Integrations (POWI) Investor presentation summary

Market opportunity and demand drivers

• High-voltage semiconductor demand tied to AI data centers, advanced chargers, electric transportation, grid modernization, electrification, automation and decarbonization.

• Applications span industrial and three-phase systems, data-center buses, 400/800/1000 V EV batteries, energy infrastructure and AC mains; 2026 addressable market estimated at $5B.

• Industrial growth drivers include renewables, HVDC transmission, battery storage, solid-state transformers, efficient motors, rail, construction, mining and electrified equipment.

High-voltage technology and products

• Proprietary PowiGaN is purpose-built for products, supports tailored designs and meets stringent automotive reliability standards; available at 1250 V and 1700 V, with 2200 V technology announced.

• PowiGaN uses a proven depletion-mode architecture, with production since 2018; presentation highlights lower wafer cost than GaN-on-silicon and SiC, high reliability and fast-switching power density.

• 2200 V PowiGaN targets data centers beyond 800 VDC, 1500 V automotive fast chargers, 1500 V utility-scale solar and battery storage, and auxiliary power for automotive and HVDC systems.

• TOPSwitchGaN extends flyback topology to 440 W, with fewer components and a smaller footprint than resonant converters; targets appliances, e-bike and tool chargers, and industrial uses.

• PowiGaN with proprietary control is presented as delivering higher efficiency than a discrete GaN design across standby and full-load conditions.

Data center and transportation applications

• 1250 V PowiGaN supports 800 VDC conversion to 54 V, 12 V or 6 V with a simpler topology; 1700 V InnoMux-2 targets compact auxiliary supplies in compute trays.

• Data-center opportunities span early 800 VDC sidecar racks and later native 800 V racks using solid-state transformers; estimated serviceable addressable market exceeds $1B by 2030.

• Higher rack power density, solid-state transformer adoption and dedicated power infrastructure are identified as drivers of expanding data-center content, including auxiliary power and conversion stages.

• EV architectures require high-voltage conversion from the main battery to subsystems including emergency power, 12 V standby supplies, steering, battery management, climate systems and onboard charging.
