PTC is a professional fabless IC design company headquartered in Taipei, Taiwan with branch offices in Hsin-Chu (Taiwan), Shenzhen (China), and Torrance (USA). PTC was listed on the Taiwan OTC (over-the-counter) market in 2001. Since its establishment in 1986, PTC has become a leader in Taiwan’s consumer IC design market. Dominant products include Multi-media Audio Controller ICs, Display Driver ICs, Home Theater Audio/Video Controller ICs, Remote Control ICs, Encoder/Decoder ICs, and ASICs and may be applied to LCD TVs, automotive multimedia devices, portable audio players, digital TVs, home audio/video appliances, and car security systems. In 2005, PTC formed a new RFIC division via outside acquisition in order to quickly meet the trend of increasing popularity of RF products in communication and home entertainment devices. As a result, PTC’s product lines have become more complete. In December of 2006, PTC obtained ISO/TS16949 certification, a standard of quality that is widely recognized by automobile manufacturers. As a consequence, the PTC-brand has gained prominence in the lucrative car-use IC market and the quality of PTC’s products has become more renowned.
