The WT7162RG is a high frequency multi-mode (QR/Valley Switching) Flyback PWM controller. It is specifically designed to work with USB PD controller to provide a total solution for USB PD or a programmable power adapter. The WT7162RG helps to improve the overall efficiency and optimize the product performance. It operates in quasi-resonant (QR) mode during heavy load and operates in discontinuous conduction mode with valley switching during light load.
