5 Summary

UCG2882x is developed to optimize the USB-PD adapter design. When used for non-USB-PD applications, the TR pin setting method needs to be changed. Instead of using TR pin to set the transformer turns ratio, when designed for non-USB-PD application, TR pin is programmed to set the reflected output voltage level based on the desired OVP threshold.
