UL/TUV standards require a clearance greater than 0.04” (1.02mm)
between input and output for Basic insulation. This issue should be
considered if any copper traces are on the top side of the user’s
board. Note that the ferrite core shown at left above is considered
part of the input/primary circuit and that the two ferrite cores shown
at the right above are considered part of the output/secondary circuit.

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.
