Beschreibung

This engineering report describes an output power supply intended for USB wall outlet charger. The 30 W output (selectable 5.1 V / 6 A or 9.2 V / 3.3 A or 15.3 V / 2 A) rail is designed for a high power USB charging with Type-A or Type-C ports. The output utilizes INN3268C from the InnoSwitch3-CP family of ICs. This design shows high power density and efficiency that is possible due to the high level of integration of the InnoSwitch3-CP controller providing exceptional performance. DER-631 is a low-line input flyback converter design. The key design goals were high power density, high efficiency, low no load consumption, and best in class thermal performance. This is intended for wall outlet USB chargers.
