If the OCP level is set to a value less than the CC limit, the inrush current upon output turning
on can easily cause an OCP trip. To avoid the current output being blocked by frequent OCP
trips an OCP delay is necessary. The OCP delay is a time interval that OCP function is
paused upon the output is turn on. The default for the OCP delay is 0.15s. This can be
adjusted according to your application. To change the delay time, please follow the
