Silicon Valley-based AnalogicTech is in talks with a number of government-approved mobile-phone manufacturers in China about procuring its power management products as part of its push into the estimated US$4 billion global market. The firm - which makes a range of semiconductor products that improve energy efficiency of electronic equipment and reduce their physical size - opened its Asia-Pacific headquarters in Hong Kong yesterday. Company president Richard Williams said the group was eyeing market opportunities from the rapid growth of the mobile phone market. 'We are looking at a market that is forecast to grow to 800 million units by 2004, with some US$6 billion worth of semiconductor business just for power management,' he said. Within Asia, China and Taiwan are estimated to account for about 70 per cent of the market, according to regional sales director for Greater China Liew Chun-meng. Analogic claims to have developed the world's smallest chip for protecting computer components from damage caused by short-circuits. The three-year-old technology firm has received more than US$1 million in orders since beginning sales earlier this year. It was studying the feasibility of using the Hong Kong office as a global sales operating centre, Mr Liew said.
