(ARK) Ark Microelectronics Co., Ltd. has been established for 13 years, and it is the only company in China that focuses on the design of depletion MOSFET. Specializing in R&D, manufacturing and sales of power devices, and providing power management and circuit protection solutions, ARK can provide high-end customized development according to customers' needs. The company focuses on the development of integrated power devices based on advanced technology and characteristic technology, and provides excellent power processing and power management capabilities by means of integrated control. It is the industry leader who constantly improves the technical level by taking application as the guide. It is ARK's consistent aim to drive innovative research and development by market demand and guide application upgrade by technological development. The series of depletion MOSFET and integrated power devices developed by the company are widely used in charger, LED, industrial control, electric vehicle, communication circuit, Internet of Things and other fields.

The founder of the company has more than 30 years of R&D and management experience in the semiconductor industry, and the team includes: Returned doctor from studying abroad, master's degree from top universities in China, and overseas R&D cooperation team. All products are independently researched and developed, and related technologies have been patented. At present, the company has nearly 70 invention patents and integrated circuit layouts, and is a semiconductor factory with independent research and development as its core competitiveness.

ARK products include industrial and consumer product lines. At present, it has extensive cooperation with TE, SAIC, FAW, Nanrui, Xuji, Star Charging, Nanjing Keyuan, Zhengwai Precision, CLP Group, etc., and in-depth cooperation with design companies such as PI, ON, IWATT, etc. It is a long-term supplier to Huawei, Glory, Samsung, Xiaomi, Google, VIVO, SONY and other customers.

ARK is used in DMX1072/DMS1072, DMX4022E/DMS4022E, DMZ1511E, DMD4523E and other products in industrial control, automotive electronics, Internet of Things and other fields. It replaces JFET devices in traditional circuits with better characteristics, and is especially suitable for transient surge suppression and over-voltage and over-current protection of high-voltage and high-current circuits. The products meet the requirements of wide temperature range, high protection level, high vibration resistance, etc., meet AEC-Q101 standard, and their performance completely reaches or even exceeds that of similar foreign products, and can be widely used in new energy fields such as electric vehicles, charging piles, photovoltaics, energy storage, rail transit, etc.

DMZ60 series, DMZ(X)10 series, DMZ15 series, DM(X)13 series, DMZ85 series, DME60 integrated dual-core and other products used in consumer electronic products such as chargers and LEDs are specially developed for PD3.1 fast charging, providing PWM IC and synchronous rectification IC power supply for PD with high power and wide voltage output, and having circuit start-up function; 30V~350V full-series enhanced MOSFET is produced overseas with higher quality, better price and more guaranteed supply compared with similar AOS products.

ARK products are compared with foreign similar products with high quality, high performance and low cost, and realize domestic substitution, which is recognized and widely adopted by domestic and foreign customers.
