iW1818, iW1830 AC/DC AccuSwitch(TM) PWM controllers use primary-side
regulation to eliminate failure-prone optocouplers while digital control
ensures cross-regulation accuracy

London UK, 28 May 2015 - Dialog Semiconductor plc (FWB:DLG), a provider of
highly integrated power management, AC/DC power conversion, solid state
lighting (SSL) and Bluetooth(R) Smart technology, today announced two power
control integrated circuits that address the most critical reliability
issue in white goods while reducing manufacturers' Bills-of-Materials (BOM)
costs without compromising power supply performance. The household
appliance market is growing at 3.8% annually and will reach 430 million
units by 2017 . Dialog's new digital controllers are designed for use in
dishwashers, refrigerators, cooking ranges, microwaves and other high
volume appliance applications.

Most appliances today use secondary-side control to maintain the tight
output voltage regulation for stable operation in multi-rail systems. For
example, a 5V output for the system microcontroller (MCU) needs ±5% voltage
accuracy, while 12V to 16V rails for motor or relay control require ±10%
accuracy. However, secondary-side designs require optocouplers, which have
significantly worse failure rates compared to other components in the power
supply.

The iW1818 and iW1830 AccuSwitch(TM) pulse width modulation (PWM)
controllers use Dialog's PrimAccurate(TM) primary-side control to eliminate
the need for optocouplers, the weakest link in achieving the high
reliability and long operating lifetime for appliances. The elimination of
a secondary-side regulator and optocoupler means reduced BOM costs and
fewer solder joints for potential failure, inherently increasing
reliability. Dialog's patented intelligent digital control loop technology
provides accurate voltage cross-regulation between the multiple power rails
in the system.

"The common notion is that primary-side regulation in white goods
applications may eliminate the optocoupler, but comes at the expense of
voltage cross-regulation accuracy," explains Davin Lee, Senior Vice
President and General Manager of the Power Conversion Business Group at
Dialog Semiconductor. "Leveraging Dialog's proven expertise in digital
control, the iW1818 and iW1830 provide the best of both worlds - higher
reliability of primary-side design and accurate cross regulation for lower
cost, longer lifetime appliance designs."

Technical Details

The iW1818 and iW1830 simplify appliance power supply designs by
integrating a high-voltage power switch (800V BJT and 700V MOSFET,
respectively) and both support high capacitance loads (up to 6,000µF) at up
to 12V.

The adaptive multi-mode PWM/PFM control in the iW1818 and iW1830
dynamically changes the switching frequency to optimise the system for high
efficiency even at light loads. They provide >80% active average
efficiency, maintain high efficiency at loads as light as 10% and achieve
< 50mW no-load standby power with fast standby recovery time. This helps
white goods designers meet global energy efficiency regulations, including
the European Ecodesign Directive and the U.S. Department of Energy (DoE)
energy conservation standards.

Both parts come in a thermally efficient, small footprint, easy-to-use
PDIP-7 package that ensures excellent thermal performance using a
single-layer PC board. In addition to built-in over-temperature protection,
they offer full protection from fault conditions, such as output
short-circuit, over-voltage and over-current.
