描述 Description

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. The WT7162RG minimizes the components counts and is available in a SOP-08 package. It provides important protection features, such as Brown In/Out, VDD OVP, OLP, OCP and Output Short Circuit Protection. Without an external LDO circuit, the WT7162RG can easily provide 3.3V~21V (7x volts) wide-range output voltage application to effectively reduce total BOM cost.
