EVAL-AD5421 - Loop Current

Hi, All.

 

Using the AD5421 Evaluation Board, was measured loop current when applying a step voltage is after SW Off → On.

After you step voltage is applied, current of about 10mA at 1.5ms width after 5.6ms has been observed.

Please tell me if there is a way to eliminate or reduce the instantaneous loop current.
