Line and load regulation is limited by duty cycle quantization and does not indicate a shift in the internal voltage reference.
For applications requiring reduced output voltage ripple and noise, consult SynQor applications support (e-mail: support@synqor.com).
If the output voltage falls below the Output DC Current Limit Shutdown Voltage for more than 50ms, then the unit will enter into hiccup mode, with a 500ms off-time.
Higher values of isolation capacitance can be added external to the module.
