Ark Microelectronics

(ARK) Established 13 years ago, Chengdu Ark Microelectronics Co., Ltd. specializes in the R&D, design, production, and sales of power semiconductor devices, while also providing power management and circuit protection solutions. As the only domestic company solely focused on depletion-type MOSFET design, ARK delivers customized high-end development services covering circuit protection solutions, product definition, design, testing analysis, and full lifecycle optimization. Guided by the principles of "driving innovation through market demands" and "enhancing applications via technological advancement," ARK's products are widely used in chargers, LEDs, industrial control, electric vehicles, communication circuits, and IoT sectors. The company's founder brings over three decades of semiconductor R&D and management expertise, with a team comprising returned overseas PhDs, top-tier university硕士生, and international R&D collaboration partners. All products are developed in-house, with nearly 70 patents (including invention patents and integrated circuit layout designs) underscoring its core competitiveness as an independent semiconductor manufacturer. ARK maintains two product lines: 1. **Consumer Electronics**: DMZ6005E, DMZ1015E, DMZ1521E series for chargers and LEDs. Notably, DMZ6005E has shipped 500 million units, specifically engineered for PD3.1 fast charging with integrated PWM IC and synchronous rectifier IC solutions supporting high-power, wide-voltage output and circuit startup functionality. 2. **Enhanced MOSFET**: 30V-350V series matching AOS counterparts with superior quality, cost efficiency, and supply reliability through overseas production. Strategic partnerships include collaborations with major design firms like PI, ON, IWATT, Lijie, Angbao,康源,华源智信,硅动力, serving as long-term suppliers to clients such as Huawei, Honor, Samsung, Xiaomi, Google, Vivo, MEIZU, ANKER, RAVPOWER, SONY, LG, and TP-LINK. For industrial and automotive applications, DMX1072/DMS1072, DMX4022E/DMS4022E, DMZ1511E, and DMD4523E series offer integrated surge suppression and overvoltage/overcurrent protection with performance exceeding international peers. Current collaborations span TE, SAIC, FAW, Nanjing Kehuan, Zhengwei Precision, and China Electronics Group. By maintaining high performance-to-cost ratios and targeting Chinese replacement, ARK's products have gained recognition and adoption globally, consistently outperforming foreign competitors in quality and reliability.
