Hi team
there is a unexpected undershoot in the output voltage waveform as the figure shown. the output voltage is 5V and the output current is about 200mA.the inductor 68uH and the output capacitor is 200uF.Yellow line is output voltage, and green line is the input voltage .Blue line is the output current. What is the cause of this issue and how to solve it?
