Dialog Semiconductor Enables Smallest, Low Power Ultrabook(TM) Adapters

LONDON & LAS VEGAS --(Business Wire)--

Dialog Semiconductor (News - Alert) plc (FWB: DLG), a provider of highly integrated power management, audio, AC/DC and short-range wireless technologies, today announced its latest move to deliver innovative solutions for Ultrabooks(TM) with the thinnest, smallest 45W and 12W travel-size power adapters that can be used with an Ultrabook. Developed by Dialog's Power Conversion Business Group (formerly iWatt Inc.), the 45W design enables Ultrabook power adapters that are less than one-half the overall volume and approximately 50% thinner than conventional 45W adapters. The 12W design enables the first compact, pocket-size adapters for an Ultrabook at just 68mm x 68mm x 17mm thick, with a typical charge time under five hours.

Dialog's ultra-slim adapter solutions complement the company's power saving technology initiatives for Ultrabooks, including SmartWave(TM) multi-touch display sensor ICs and highly integrated, next-generation power management and audio solutions.

Dialog's 45W and 12W designs support Intel (News - Alert)(R) Turbo Boost Technology with 82W peak power capability at 10% duty cycle for the 45W adapter and 2% for the 12W adapter. They also easily meet, or exceed emerging, stringent global energy standards for lower standby power and higher light-load and active average efficiency in power adapters, including the proposed stringent European CoC version 5(1) and U.S. DoE(2) regulations. The 45W design provides high, 90% active average efficiency and achieves < 100mW no-load standby power with fast standby recovery time. The 12W design provides 86% active average efficiency and achieves < 50mW no-load standby power with fast standby recovery time. Both designs maintain high efficiency at loads as light as 10%.

The 45W ultra-slim design uses Dialog's iW1762 digital pulse width modulation (PWM) controller in a PC board that fits in a 61 cubic centimetre (cc) adapter case and is up to one-half the size of conventional 45W power adapters, which can be as large as 168cc, or more. The 12W design uses Dialog's iW1760 PWM controller in a PC board that fits in a pocket-size 80cc adapter case.

Volex pc provides the enclosure design for both the 45W ultra-slim and 12W travel adapters.

'Dialog's Power Conversion Business Group is best known for reducing size and power consumption in power adapters for smartphones and tablets,' according to Mark Tyndall, Senior VP Corporate Development and Strategy, General Manager of the Power Conversion Business Group at Dialog. 'Applying this expertise to higher-power class adapters, Dialog is the first supplier to deliver incredibly slim, ultra-light charger designs that users should expect with next-generation Ultrabooks.'

The iW1762 and iW1760 digital PWM controllers use Dialog's PrimAccurate(TM) primary-side control technology. PrimAccurate control eliminates the need for a secondary-side regulator and opto-isolator, reducing the bill of materials (BOM) costs, improving line-voltage surge protection, and delivering overall rugged performance.
