描述 Description

The WT7160RM is a high performance multi-mode (CCM/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 WT7160RM helps to improve the overall efficiency and optimize the product performance. It operates in continuous Current Mode (CCM) during heavy load and operates in discontinuous conduction mode with valley switching during light load. The WT7160RM minimizes the components counts and is available in a SOP-8 package. It provides important protection features, such as Brown In/Out, Vo UVP, VDD OVP, OTP, OLP, OCP and Output Short Circuit Protection. Without an external LDO circuit, the WT7160RM can easily provide 3.3V~21V (7x volts) wide-range output voltage application to effectively reduce total BOM cost.
