  • RE: TPSM831D31: How to build a project in Fusion Digital Power Designer?

    Hi Fushen, Changing the switching frequency (FSW) will modify how fast the controller will respond to load changes. Setting FSW value too low will lead to poor transient load performance, while making FSW too high will lead to controller instability…
