Its products support high voltage and high current scenarios, such as in car charging systems (OBC) and electric drive control, and have passed automotive level certification (such as AECQ100).
Maxim Integrated
Known for its low power consumption and compact design, its products occupy an important position in the wearable device and TWS earphone markets. For example, Maxim's ultra small PLC devices can save 80% of circuit area and meet high-density design requirements.
Silergy
Focusing on high-performance power management chips, particularly outstanding in the fields of fast charging and smart homes. Its product achieves single-chip integration in the TWS earphone charging case solution, simplifying circuit design and reducing costs.
2、 Representative domestic brands
Chipown
National level specialized and innovative "little giant" enterprise, focusing on the fields of home appliances, industrial control, and new energy vehicles. Its core products include high-voltage ACDC chips and intelligent power drive chips, which have entered the supply chains of leading home appliances such as Midea and Gree, and have achieved domestic substitution in the field of on-board charger (OBC) chips.
Shanghai Beiling
The original IDM model has been transformed into Fabless Design Company, with products covering LDO, DCDC, and automotive grade power management chips. In 2023, its vehicle grade LDO and LED driver chips will be sold in bulk, and SiC power devices will be deployed to enhance competitiveness in the industrial and automotive markets.
Sino Wealth Technology
A leading domestic manufacturer of automotive power management chips, whose products have passed ISO 26262 functional safety certification. Its boost flyback controller SCT81621Q breaks through the bottleneck of 60V high voltage technology and is applied in intelligent cockpit and ADAS systems, with performance benchmarking against international first-line brands.
SG Micro and Yutai Semiconductor
Shengbang has expanded its product line through the acquisition of Yutai Semiconductor. Yutai's PowerSOC solution has performed outstandingly in the TWS headphone market, with single-chip integrated charging, discharging, and protection functions. Customers include JBL, Anker, and others.
Hongmao Semiconductor
Focusing on cost-effective power management solutions, our products include lithium battery charging, LDO, and LED driver chips. Its HM6234 low dropout linear voltage regulator chip is suitable for smart wearables and IoT devices with an ultra-low static current of 0.3 μ A and a ripple suppression ratio of 70dB.
3、 Emerging and segmented brands
SiPower Semiconductor: Deeply cultivating TWS headphone battery management, launching the SY880X series intelligent charging compartment solution, with customers including OPPO and Xiaomi.
LY Semicon: Covering the consumer electronics and medical device markets, its product line includes DCDC boost/buck chips and lithium battery protection ICs, with annual sales exceeding 90 million yuan.
Bright Power has technological advantages in the fields of LED drivers and fast charging chips, with R&D investment accounting for over 10% in 2023, accelerating its transformation towards high-end industrial and automotive markets.
Market Trends and Localization Opportunities
Domestic substitution acceleration: The market size of China's power management IC is expected to reach 23.45 billion US dollars by 2025, with domestic manufacturers accounting for less than 20%. Home appliances, industrial control, and automotive electronics have become the main battlefield for substitution.
Technological upgrade direction: Transforming from low-end consumer electronics to high reliability industrial and automotive grade chips, SiC/GaN wide bandgap semiconductor technology has become a research and development focus.
Industrial chain collaboration: Domestic enterprises integrate wafer foundry and packaging resources through the Fabless model, while Xinpeng Microelectronics invests in FAB factories such as Huarui Microelectronics to ensure production capacity. Shanghai Beiling relies on Huada Semiconductor to strengthen its power device layout.
Summary: International brands occupy the high-end market through technological accumulation, while domestic manufacturers gradually break the monopoly by focusing on segmented fields (such as home appliances, TWS headphones, new energy vehicles) and differentiated innovation. In the future, with increased policy support and R&D investment, domestic power management ICs are expected to achieve greater breakthroughs in high value-added markets such as automotive grade and industrial grade.
