Sinopower

What Sinopower does

Sinopower Semiconductor Inc. (大中積體電路股份有限公司) is a fabless power semiconductor design company founded in August 2008 and headquartered at Hsinchu Science Park, Taiwan, with a sales and marketing office in Zhonghe District, New Taipei City. The company designs MOSFET and IGBT discrete devices and high-voltage integrated circuits (HV IC), organized across low-voltage (≤40V), medium-voltage (60V-250V), and high-voltage (>250V) categories, with DrMOS integrated driver-MOSFET power stage products for computing/server regulation and AEC-Q101-qualified MOSFETs in the LV and MV segments for automotive and EV applications. Its reported intellectual property base comprises 50+ world patents accumulated over 15+ years of product development.

The business is structured as a fabless designer that monetizes through hardware sales of proprietary IC designs, with a headcount of approximately 96 employees as of the December 2025 satisfaction survey. Go-to-market is B2B and channel-led: products move through an authorized distributor network covering Taiwan (Weikeng, Sun Unique, Hanwei, EDOM, Gredmann, Sunshine Global), mainland China (Key Source, CINVI, Huahai, Shenzhen Tengqiu), Southeast Asia (IC Resource, Singapore), Korea (ChipForU), and Europe (TRG Components, Germany), supplemented by direct sales support from Hsinchu headquarters and a New Taipei City sales office. Pricing is quote-based rather than list-published, reflecting industrial B2B conventions.

The company serves nine application segments: PC and server, industrial automation control, handheld devices, automotive (EV chargers, EVs, automotive electronics), LCD monitors, motor drives (fans, e-bikes, drones), information and communication (5G base stations, network routers), battery modules, and switching power supplies. Anpec Electronics Corporation is the largest shareholder at 42.60% ownership, embedding Sinopower within Taiwan's broader power semiconductor ecosystem. The company has been listed on the Taiwan OTC market (stock code 6435) since January 7, 2016, and has its stock affairs handled by Taishin Securities, with 4 of 7 board seats held by independent directors. Reported revenue was NT$3.40 billion in 2025 (+25.24% YoY), placing the company among Taiwan's mid-tier IC design houses (ranked #34 in IC design and #740 in manufacturing in Commonwealth Magazine's 2025 Top 2000).
