描述 Description

Single-chip power and communication IC; up to 7.5W
The iW1680 is a single-chip solution that supports 5W and 7.5W output power and uses Dialog's intelligent Rapid Charge™ digital algorithm and digital PrimAccurate™ primary-side control to significantly reduce charge times in USB AC/DC power adapters with no additional bill of materials cost versus slower conventional charging technologies.
The iW1680 is highly efficient, and offers no-load standby power <30mW, meeting the US Department of Energy's external power supply efficiency requirements and Version 5, Tier 2 of the EU’s Code of Conduct for external power supplies.  The iW1680 also offers a full array of protection features including overvoltage, short circuit and over-temperature protection.
