On November 27, 2025, a major announcement was made in the semiconductor industry – Halo Microelectronics Group completed the acquisition of a 55% stake in Chengxin Microelectronics for 310 million yuan. The transaction adopted a combination of “55% equity + 45% cash,” clearly demonstrating its strategic intention to strengthen its position in the power management chip field. This acquisition not only became a focus of industry attention but also confirmed the core value of power management chips as the “energy center” of electronic devices and the inevitable trend of increasing market concentration. As a professional manufacturer deeply involved in the power chip field, ABL Semi (ABL Semiconductor) paid close attention to this and consistently responded to market demands with technological innovation and a full-scenario layout.
The underlying logic of mergers and acquisitions: Power management chips become a core necessity.
Halo Micro’s acquisition is interpreted by the industry as a typical example of horizontal integration—by incorporating Chengxin Micro’s product system and customer resources, the application scenarios of its power management chips will expand from the previously concentrated mobile phone field to more dispersed industrial and consumer electronics scenarios, while simultaneously achieving synergistic optimization of R&D resources and the supply chain. Behind this move is the explosive growth of the global power management chip market: the rise of emerging fields such as AI computing devices, smart cars, and new energy terminals is driving the upgrade of chip demand from “basic power supply” to “high-efficiency energy saving and intelligent control.”
According to industry data, the global power management chip market size is expected to exceed $70 billion by 2025, with demand related to automotive electronics and AI servers growing by over 30%. Automotive-grade power chips are showing a trend of “doubling the usage per vehicle” due to the increased penetration rate of intelligent driving—the number of power management chips installed in mid-to-high-end new energy vehicles is already 2-3 times that of traditional fuel vehicles, and the demand for high-end autonomous driving models exceeds 100 chips per vehicle. This market opportunity is precisely the core strategic focus of ABL Semi for many years.
ABL Semi: Leading the Power Chip Segment with Technological Accumulation
Compared to a development path that relies on mergers and acquisitions to quickly fill gaps in capabilities, ABL Semi has consistently adhered to a strategy of “independent R&D of core technologies + full-scenario product iteration,” accumulating significant technological barriers and a strong market reputation in the power management chip field. Regarding the two most pressing market areas—automotive-grade and AI computing power supplies—ABL Semi has developed a mature product portfolio and solutions.
Automotive-grade power chips: Dual guarantee of compliance and reliability
Leveraging its deep understanding of the harsh automotive environment, ABL Semi’s automotive-grade DC-DC and LDO chips have fully passed AEC-Q100 certification, covering a wide operating temperature range of -40℃ to 150℃, perfectly adapting to core scenarios such as smart cockpits, ADAS domain controllers, and battery management systems (BMS). Among them, the high-voltage power supply chip developed for the three-electric systems of new energy vehicles integrates overcurrent, overtemperature, and reverse polarity protection functions, with a quiescent current as low as μA, improving power supply stability while reducing energy consumption. Its technical indicators are comparable to those of leading international brands. Currently, ABL Semi’s automotive-grade chips have entered the supply chain systems of several major domestic automakers, safeguarding the safety of intelligent driving.
AI and Computing Power Power Solutions: Efficiently Matching Explosive Computing Power Demand
Addressing the high current power demands of AI servers and GPU computing cards, ABL Semi’s new generation of non-isolated DC-DC chips offers a continuous output current of up to 50A per chip, with multiple chips connected in parallel to meet 100A-level power requirements. Power conversion efficiency exceeds 95%, significantly outperforming the industry average. This series supports the PMbus intelligent communication protocol, enabling real-time response to dynamic changes in computing load, providing precise and stable power supply to AI edge computing devices, smart cameras, and other terminals. It is already being used in mass production projects by leading domestic AI computing equipment manufacturers.
Full-scenario coverage: from consumer electronics to industrial control
While consolidating its advantages in automotive-grade and AI fields, ABL Semi’s power management chips have been widely applied to diverse scenarios such as consumer electronics (smartphones, smart wearables), industrial control (PLCs, robotic arms), and smart homes, forming a product system of “general-purpose chips + customized solutions.” ABL Semi can provide end-to-end services from chip design and sample testing to mass production delivery to meet the needs of customers in different industries. With its flexible supply chain responsiveness, it effectively reduces customers’ R&D cycles and procurement costs.
Seize the opportunity for integration and jointly explore new possibilities for power chips
The acquisition of Halo Microelectronics has heralded a shift towards “efficiency upgrades” in the power management chip industry, while technological innovation and in-depth application scenarios remain the core logic for companies to thrive. ABL Semi will continue to increase its R&D investment, focusing on technological breakthroughs in high-end fields such as automotive-grade and AI computing power, while also adopting a more open approach to cooperate with upstream and downstream companies.
