Dialog Semiconductor Plc.: Dialog Semiconductor Enters White Goods Sector with Expanded Power Conversion Product Portfolio (news with additional features) - Seite 2

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.
