WT7131 SOT-26同步整流替換MP6908 Weltrend偉詮

The WT7131 is a high-performance synchronous rectification controller. It is used to control a secondary-side synchronous rectification MOSFET in a flyback switch mode power supply. Without external auxiliary winding supplies, the WT7131 can easily provide power to the VDD. It can be powered by either the VIN or VD pin.

The WT7131 built-in several circuits to minimize external part counts and overall total system cost.
