Report Predicts Digital Power Is Years Away

Volume shipments of digitally-controlled power supplies are likely to be at least two years away according to the latest IMS research (www.imsresearch.com) forecasts in The Worldwide Market for Power Supplies - 2006. “Despite significant recent media attention, global revenues for ‘full digital’ products are not expected to exceed $100 million until at least 2009, whilst penetration for ‘hybrid digital’ products is forecast to be much greater, though still several years away”, commented report author Ash Sharma.

The recently published report estimates the merchant power supply market to have been worth $13.6 billion in 2005 and is forecast to achieve modest growth between 2006 and 2011. Strongest growth is forecast for the ac-dc market driven by strong demand for external adapters and chargers from consumer applications and notebooks as well as continued investment in the IT sector. Weaker growth is forecast for the dc-dc converter market due to intense price erosion, encroachment of discrete solutions and reduced demand from certain key application sectors.

The Worldwide Market for Power Supplies contains latest forecasts for both the ac-dc and dc-dc markets based on 2005 sales data with independent and objective projections for ‘digital power’. The report also includes 2005-2011 forecasts for the market by package type, geographic region, power ratings, application sectors and architecture. In addition, a number of market share estimates are provided.
