Designed to deliver more powerful, small form-factor smartphones and tablets, Dialog Semiconductor plc has expanded its power adapter line in order to replace conventional power supplies.
Dialog’s iW671 replaces Schottky diodes used in conventional supplies with a more efficient MOSFET that works along with other primary-side controllers to deliver efficiency up to 88 percent, Dialog claims. This allows for a higher power density needed in powerful, small form-factor mobile devices without exceeding thermal limits.
Dialog said the iW671 is designed to work for 15 W and 50 W output power and allow for enabling chargers and adapters to meet global energy standards such as the 2014 U.S. Department of Energy and European CoC tier 2 regulations.
“With global energy regulations for power consumption becoming more and more stringent, power supplies are being pushed to their cost, performance and size limits,” said Davin Lee, Senior Vice President and General Manager of the Power Conversion Business Group at Dialog Semiconductor, in a statement. Lee added that the iW671 will provide designers “the ultimate combination of higher efficiency, faster standby recovery performance and a reduced BOM for a new generation of low cost adapters and chargers.”
