USB PD Power Supply/Module ATS
8000 Series

The USB 3.1 specifications has three major features which are 10Gbit/s transmission speed, USB PD (Power Delivery) with support for 100 watt charging power, and the standard Type-C connector/cable that can be inserted with either side. It is expected to meet all kinds of data / video transfer applications. The advent of USB PD may consolidate the specifications of various power converters and the laptop, monitor, printer or Hub that implements USB PD is no longer a simple power-consuming device but able to supply power to other devices. The USB PD DRP (Dual role port) function allows the built-in USB PD module to deliver a maximum of 100 watts of power through the Type-C interface. To make sure the USB PD Type-C output power does not supply invalid voltage or poor power output characteristics with excessive noise that can damage the power consuming device and cause unsuccessful startup, each USB PD power supply or module has to be fully tested during production to ensure the product features meet the design specifications. This ensures high-quality products are provided to the market to gain acceptance.
