WT7131A 封装SOT23-6高性能同步整流控制器 Weltrend伟诠

The WT7131A is a high-performance synchronous rectification controller. It is used to control a secondary-sidesynchronous rectification MOSFET in a flyback switch mode power supply. Without external auxiliary windingsupplies, the WT7131A can easily provide power to the VDD. It can be powered by either the VIN or VD pin. TheWT7131A built-in several circuits to minimize external part counts and overall total system cost.
