What Chipown does

Chipown (Wuxi Chipown Microelectronics, ticker 688508.SH) is a fabless power-semiconductor IC design house founded in 2005 and listed on the Shanghai STAR Market in 2020. The company designs analog and mixed-signal power management, driver, and power device products covering AC-DC, DC-DC, gate drivers, SiC and GaN wide-bandgap devices, intelligent power modules (IPM), and integrated power modules, with more than 2,000 chip models, 300+ IP assets, and 100+ invention patents. Its end markets span smart home appliances (the historical core, with Midea Group cited as a key customer), AI server and data-center power conversion, industrial power and motor control, new-energy vehicles, and photovoltaic / energy-storage / charging applications. The company holds ISO 26262 ASIL D functional-safety and AEC-Q100 automotive qualifications, positioning it for safety-critical and high-voltage use cases.

Chipown operates a fabless model, monetizing through chip sales to OEM and module-maker customers, with a sales and technical-support footprint of seven offices across China — Wuxi (HQ), Suzhou and Shanghai (R&D), Shenzhen (sales), and Zhongshan, Qingdao, and Xiamen (technical support laboratories). The 2025 R&D spend of RMB 258M, equivalent to 22.60% of revenue and up 14.22% YoY, indicates a design-intensive cost structure aimed at sustaining the high-voltage GaN and SiC roadmap. Recent product activity (2026) — including the PN7924 800V GaN half-bridge driver, the PN719XS/PN729XS/PN739XS SiC HB-IPM series, and an 800V HVDC three-stage power-supply full-stack solution (PN68XX, PN786X, PN788X/PN7893, PN685X) — demonstrates a deliberate pivot from low-voltage appliance power toward AI compute power and NEV / industrial high-voltage applications. Commercial strategy is anchored on reference-design wins with Tier-1 OEMs and ecosystem participation such as the Wuxi 'AI+ Manufacturing' Innovation Alliance.
