The AC to DC adapter industry is in an exciting time where the interoperability of devices is increasing, as more is required from power adapters. The change in environment has accelerated the evolution of power adapter design for mobile devices, from the days of proprietary wall warts and bricks, to the latest challenges presented by USB-C Power Delivery standard and COC Tier 2 efficiency requirements. These new technical challenges are coupled with the charger use changing from a device that was plugged in the corner, to a necessary accessory. With adapters forced into the spot light, consumers are now demanding smaller, aesthetically pleasing, charges with small charge times. To help designers solve today’s challenges, several new solutions will be presented, including High frequency Quasi-Resonant (QR) Flyback and Active Clamp Flyback (ACF).
Key Points to be Discussed:
1. Current market trends for Mobile Devices
2. How adapter design evolved to meet government regulations
3. How to move to the next level of efficiency
4. The move toward universal smart power charging
