Note 1: Line and load regulation is limited by duty cycle quantization and does not indicate a shift in the internal voltage reference.

Note 2: For applications requiring reduced output voltage ripple and noise, consult SynQor applications support (e-mail: support@synqor.com)

Note 3: 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.

Note 4: Higher values of isolation capacitance can be added external to the module.

Note 5: Additional 25ms between enable and start of Turn-On time for N logic full-featured units to set up communication.
