Qualcomm® Quick Charge™ Adapter Solutions

Dialog's Qualcomm Quick Charge™ 2.0 and 3.0 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.
