What SG Micro does

SG Micro Corp (SGMICRO) is a Chinese fabless semiconductor company specializing in high-performance analog integrated circuits for analog signal conditioning and system power management. Founded in 2007 and headquartered in Beijing's Haidian District, the company designs and distributes a broad portfolio of analog and mixed-signal ICs (amplifiers, data converters, voltage references, interface ICs, analog switches, temperature sensors, RF products, AMR sensors) and power management ICs (DC/DC switching regulators, LDOs, MOSFETs, GaN FETs, battery management ICs, LED drivers, motor/gate drivers, PMUs, and power modules). The company has developed proprietary technologies in AMOLED display power management with SIDO topology supporting LTPO and Tandem displays, AEC-Q100 qualified automotive-grade converters, precision 16-bit SAR ADCs, and PMBus-enabled hot-swap controllers for compute infrastructure.

The company serves six primary vertical markets: industrial, automotive, communication, computing, consumer electronics, and medical equipment, with product pricing ranging from $0.32-$28 per unit depending on complexity and volume tier. SG Micro operates a distributor-led go-to-market model, selling through a global network of authorized distributors including Arrow Electronics, Avnet, WPG, Macnica Galaxy, and Serial Microelectronics, supplemented by direct sales offices across 13 Chinese cities plus Hong Kong, Frankfurt, and Tokyo. Free sample programs, parametric search, and cross-reference tools on the company website target design engineers at the top of the funnel.

The company is dual-listed on the Shenzhen Stock Exchange (300661.SZ) and completed its Hong Kong Stock Exchange listing (03661.HK) in June 2026, raising HK$4.60 billion (approximately US$590 million). With 1001-5000 employees and 2025 revenue growing 16% year-over-year, SG Micro is positioned as one of China's leading domestic analog IC suppliers competing against established global players like Texas Instruments, Analog Devices, and Maxim Integrated in industrial, automotive, and consumer applications.
