iW1770 peak power mode technology eliminates need to oversize power supply
components and heat sinks for high power density designs

London UK, 01 October 2014 - Dialog Semiconductor plc (FWB:DLG), a provider
of highly integrated power management, AC/DC, solid state lighting and
Bluetooth(R) Smart wireless technology, today announced the release of its
new iW1770 PrimAccurate(TM) primary-side controller that offers a 60W peak
power mode from a 40W supply, eliminating the need to oversize the power
supply design and enabling compact, light-weight, high power density
adapters for Ultrabooks(TM), network devices and other home electronics
products.

Conventional power supply designs must be sized to match the peak (maximum)
power requirements of the system, which may be significantly higher than
the normal system operating power. Dialog's patent-pending peak power mode
technology used in the iW1770 provides peak power higher than the maximum
continuous output power for a pre-determined period of time, without the
need to oversize the power supply transformer and output capacitors. This
enables designers to produce higher power adapters that are the same size
and cost as power supplies with a nominal rating of 40W.

"Power supplies have a continuous output power range, on which the thermal
and electrical design must be based," explains Davin Lee, Senior Vice
President and General Manager of the Power Conversion Business Group at
Dialog Semiconductor. "Instead of designing to match the peak power
requirements of the system, the iW1770 lets designers create smaller,
thinner and lighter-weight power supplies."

With an average output power range of 15W to 40W and the ability to handle
peaks up to 60W, the iW1770 also offers less than 50mW no-load standby
power consumption, fast dynamic load response and high efficiency. This
allows power adapters to meet stringent global energy standards including
the final 2014 U.S. DoE(1) and European CoC version 5, tier 2(2)
regulations.

The iW1770 includes a user-configurable, five-level cable drop compensation
option to eliminate the ordering and inventory challenges of stocking
multiple product versions for various output voltage needs. It comes in a
