RDK-659: 30W, 5.1 ~ 15.3V @ Up to 6A, 180 ~ 265 VAC in

Summary

The RDK-659 evaulation board is an output power supply intended for a 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.

RDK-659 is a high-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.
