Princeton Technology Corp

ptc-logo PTC is a fabless IC design company headquartered in Taipei, Taiwan with R&D centers in Hsin-Chu (Taiwan) and the USA, subsidiaries in Shenzhen (China) and Chengdu (China), and a branch office in Japan. PTC has been listed on the Taiwan OTC (over-the-counter) market since 2001.

Since its founding in 1986, PTC has become a leader in Taiwan in consumer IC design. In the highly competitive automotive IC market, PTC has established a reputation for superior quality, having numerous products certified and adopted by prominent automobile manufacturers. PTC’s products include Display Driver ICs, Multimedia Audio Controller ICs, Motor Driver ICs, RF ICs, Encoder/Decoder ICs, Remote Control ICs, and ASICs and are suitable for a wide range of applications, including automotive dash-board and multimedia devices, portable audio players, digital TVs, home audio/video appliances, DSCs, DSLRs, monitoring cameras, and car security systems.

More recently, in response to the rise in importance of Green Power (Energy Conservation), PTC has invested in developing IC technology for energy-saving solutions and has successfully designed a series of energy-saving Ballast Driver ICs, LED Lighting/Backlight Driver ICs, and BLDC (Brushless DC) Motor ICs, which can be applied to a variety of indoor/outdoor lighting and motor control products.

PTC has accumulated many years of IC design experience and most recently has been involved heavily in the development of MCU (Microcontroller Unit) products. Nimble execution of product strategies to meet market trends and strong support from the world’s leading foundry partners allow PTC to continually launch new products and effectively enter emerging markets.
