The recent slide in Power Integrations after a return to profit raises a sharper issue. Are investors reassessing the business, or did sentiment simply swing too far, too fast ahead of current valuation levels?

Most Popular Narrative: 35% Undervalued

On the most followed valuation view, Power Integrations screens as undervalued, with a fair value estimate of $71.75 against the last close at $46.80, pointing to a wide gap that hinges on how the higher voltage product roadmap plays out.

Power Integrations' proprietary high-voltage GaN technology, now extending from 750–1700 V up to 2,200 V and reaching into applications that have used silicon carbide, supports premium positioning in higher power systems and has the potential to lift average selling prices and gross margins.

AI data center power opportunities, including auxiliary supplies for NVIDIA’s 800 V racks using 1,700 V InnoMux-2 ICs and a longer-term path into the main GPU power stage within a serviceable data center market sized at about US$1b by 2030, set up new content drivers for revenue and earnings.
