Beschreibung
This design note describes a 15 W, universal AC mains, isolated Quasi-Resonant flyback converter compatible with Qualcomm’s High Voltage Dedicated Charging Port Quick Charge 3.0 Class A specification. The converter provides adjustable output voltage in a range from 3.6 Vdc to 12 Vdc. It maintains maximum output power 15 W at full range of the voltage output and at same time it limits the maximum output current to 2.0 A. The design is targeted for smart phone and tablet charger applications. The charger design utilizes ON Semiconductor’s new NCP4371 Qualcomm Quick Charge 3.0 Controller, NCP1361E Quasi-Resonant Controller and NCP4305 Synchronous Rectification controller.
