NCP1247USBPDGEVB: Fixed Frequency Current Mode PWM Controller Evaluation Board

The NCP1247USBPDGEVB evaluation board is a flyback-topology switched-mode power supply designed for USB PD (power delivery) applications. It works in input voltage range from 90 Vac to 265 Vac and provides the output voltages 5 V, 12 V and 20 V up to 3 A of output current. The regulation of switched-mode power supply is ensured by the NCP1247 – a new fixed frequency current mode PWM controller with HV startup. The output voltage value (5 V, 12 V or 20 V) is set by the MCU controller CYPD1132-16SXI. The CCG1 Host Board from Cypress Semiconductor can be used for an easy demonstration how the power supply for USB PD application works. Communication between the NCP1247USBPDGEVB evaluation board and CCG1 Host Board is ensured by a USB Type-C cable (it uses the CC wire for communication and the VBUS wire for energy transmission).
