Dialog Semiconductor expands AC/DC portfolio Dialog Semiconductor has announced the availability of its digital Zero Voltage Switching (ZVS) chipset to enable 100W and beyond High Power Density (HPD) Power Supply Units (PSUs) that are 30-50% smaller than conventional high power PSUs. AC/DC converters have been challenged by thermal constraints associated with the efficiency of the device, but with Dialogâs ZVS chipset, designers will be able to reduce component size and BOM cost to enable smaller form-factor, lighter weight power supplies, including travel adapter...
