AC/DC Rapid Charge™ Solutions

Enabling faster charging of portable devices

As the leader in AC/DC Rapid Charge™ solutions, we support more smartphone fast charging protocols than any other supplier. Our SmartDefender™ advanced hiccup technology reduces power dissipation in cables and connnectors during over current conditions, helping to improve safety and reliability in USB power adapters for smartphones and tablets.

Qualcomm® Quick Charge™ Adapter Solutions

Dialog's Qualcomm Quick Charge™ adapter solutions offer inherently higher efficiency to enable the higher power density needed for smaller form-factor, fast charging power adapters. They provide the best combination of low cost and small size with high efficiency. Adding Dialog’s synchronous rectifier boosts efficiency as high as 90%, while eliminating the need for a parallel Schottky diode.
