Note 1: Output is terminated with 1 µF ceramic and 15 µF low-ESR tantalum capacitors. For applications requiring reduced output voltage ripple and
noise, consult SynQor applications support (e-mail: support@synqor.com)
Note 2: 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,
Note 3: Line and load regulation is limited by duty cycle quantization and does not indicate a shift in the internal voltage reference
