NCP1342PD65WGEVB
NCP1342 60 W USB PD Evaluation Board

The NCP1342PD65WGEVB showcases the NCP1342 Quasi-Resonant Flyback Controller in a USB Power Delivery (PD) application.

 

The evaluation board delivers 60 W of power using a compact RM8 transformer. The NCP1342 is suitable for designing high-performance off-line power converters and USB PD adapters, and features Rapid Frequency Foldback (RFF) for improved efficiency over the load range. An integrated active X2 capacitor discharge feature eliminates discharge resistors which enables no-load power consumption below 40 mW
