Advantages of Digital Control

Ultimate Monitoring and Flexibility：This is the core advantage of digital control. Through built-in communication interfaces, active system units can monitor voltage, current, power, and temperature in real time with high precision. This transforms the power supply into an “intelligent node” that can seamlessly connect to data center management systems, enabling predictive maintenance and dynamic energy efficiency optimization.
High Precision and Programmability：With digital loop control and a graphical user interface (GUI), engineers can configure hundreds of parameters such as switching frequency, protection thresholds, and timing sequences without repeatedly soldering resistors and capacitors. Meanwhile, digital control delivers PWM resolution at the hundreds of picoseconds level, allowing for finer adjustment of the output voltage.
Software-Defined Efficient Development：After adopting digital control, a single hardware platform can be adapted to diverse requirements through software upgrades, greatly shortening the development cycle and accelerating time-to-market for customers’ products.

Hynetek ‘s digital control IC products have been successfully commercialized, verified and validated by key customers, and entered international manufacturers through their product chains. Its core advantages lie in power conversion efficiency and software programmability.

Digital control enables cycle-by-cycle precise regulation and adaptive response to load variations without relying on external compensation networks. This not only simplifies the design process but also supports power supply requirements in other complex scenarios.

With the full digitalization of power system management in application areas represented by data centers, new energy vehicles and other fields, digital control combined with high-performance power devices is becoming the mainstream technology for high-power power supplies.

Hynetek’s products can form strong synergy with driver chips and the Company’s high-performance power device products, filling the domestic shortage of high-end digital energy control chips.

For Oriental Semiconductor’s extensive existing customer base in high-performance power supplies, the Company will provide overall solutions based on high-performance power devices plus digital control ICs, delivering greater value to customers.

Industrial Synergy: Building a Golden Triangle of “Control – Drive – Execution”

Oriental Semiconductor ‘s strength lies in its high-performance “execution” units — high-performance power devices, while Hynetek provides the top-level “control” units (digital control ICs) and key “drive” units.

Combined, the three form a complete “control-drive-execution” full-link solution spanning signal processing, logic control and power output.

This will help the company upgrade from a pure supplier of power devices to a provider of system solutions for next-generation digital energy management systems.

Upon the completion of this transaction, both parties are expected to fully leverage synergies.

Relying on Hynetek’s outstanding R&D team (whose core members are from world-leading power IC designers including Analog Devices (ADI) and Texas Instruments (TI), with nearly 20 years of experience in digital power development), as well as the Company’s device technology, brand and channel resources, the two parties will jointly promote products to enter high-potential markets for next-generation digital energy management systems and provide integrated solutions ranging from chips to modules.

This transaction will help the Company continuously enrich its product portfolio and consolidate its core competitiveness. It aligns with the Company’s long-term strategy and industry development trends, laying a solid foundation for the enhancement of long-term corporate value and high-quality development.

Upon the completion of this transaction, Hynetek will become a consolidated subsidiary of the Company and be included in the scope of the Company’s consolidated financial statements. The transaction will be funded by the Company’s own funds and/or self-raised funds (including bank borrowings). It will not affect the Company’s normal production and operation, nor will it have a material adverse impact on the Company’s financial position and operating results. There is no circumstance impairing the interests of the Company and its shareholders, especially minority shareholders.
