iW662

Integrated Secondary-Side Synchronous Rectifier Controller and RapidCharge™ Interface IC for Qualcomm® Quick Charge™ 3.0 and 2.0 Applications

A team of engineers is ready to answer your questions

Uses Dialog’s XM-Comm Technology to Remove All Optocouplers from Rapid Charge Solutions

The iW662 integrated secondary-side synchronous rectifier controller and rapid charge interface IC uses Dialog’sXM-Commtechnology to communicate back to the primary-side controller, the (iW1790,iW1796,iW1798) eliminating the need for optocouplers to create solutions for rapid charging protocols such as Qualcomm Quick Charge 3.0 and 2.0 technology.

The device also integrates a synchronous rectifier controller that uses adaptive off-time control to remove the need for a parallel schottky diode to reduce power loss during transitions. The total solution reduces overall BOM cost and improves efficiency in reduced form-factor travel adapters.

The iW1790+iW662 chipset uses Dialog's advanced fault control technology to help address soft shorts in cables and connectors. Learn more about advanced hiccup technologyhere.

Qualcomm® Quick Charge™ is a product of Qualcomm Technologies, Inc.
