Power Integrations stock is tied to a new CAPZero 4 product line launched in September 2026, while a published long-range scenario projects revenue of USD 690.7 million and earnings of USD 160.0 million by 2029. The company is developing the product for industrial and consumer AC-DC applications.

CAPZero 4 targets lower power use

According to Yahoo Finance on September 23, 2026, Power Integrations launched its fourth-generation CAPZero 4 X-capacitor discharge integrated circuits during September 2026. The devices are specified for power consumption below 1 mW and operation from minus 40 degrees Celsius to 125 degrees Celsius.

The product also carries global safety compliance for industrial and consumer AC-DC applications, according to Yahoo Finance. For the stock, the commercial question is whether the new device can translate efficiency specifications into broader design wins and revenue over several reporting periods.

Long-range figures set the test

The same September 2026 coverage places the company at a projected USD 690.7 million of revenue and USD 160.0 million of earnings in 2029. Those figures provide a quantified comparison point against the current business, but they are a long-range projection rather than reported 2026 results.

Power Integrations designs and markets analog and mixed-signal integrated circuits for high-voltage power conversion, including applications in everyday electronics and industrial equipment, according to Simply Wall St on September 23, 2026. This makes the sub-1 mW specification a product-level figure, while the USD 690.7 million revenue projection is the broader valuation reference.

Stock remains linked to execution

The September 2026 launch gives Power Integrations a concrete operating milestone, but the 2029 projection also highlights the distance between product introduction and financial delivery. The comparison is clear: the launch specifies less than 1 mW of consumption, while the long-range scenario specifies USD 690.7 million of revenue and USD 160.0 million of earnings.

Power Integrations stock trades on Nasdaq under the ticker POWI. The September 2026 product update leaves design adoption, revenue conversion and earnings delivery as the measurable factors for later results.
