 Output Overshoot
 

 

 

When power adapter start to work, the output voltage will increase to a value  V1,following it will be adjusted to a stable output value V0 through feedback loop,the output overshoot is (V1-V0) /V0*100%; similarly,when power adapter disconnected output,output undershoot will occur.

 

This parameter mainly shows feedback loop's reaction rate of power adapter.

Input conditions and load conditions should be considered when testing power adapter's Ouput Overshoot.
