Note 1: Converter will undergo input over-voltage
Note 2: UL’s product certification tests were carried out using 12.5 A fast blow fuse. Fuse interruption characteristics have to be taken into account while
designing input traces. User should ensure that Input trace is capable of withstanding fault currents.
Note 3: For applications requiring reduced output voltage ripple and noise, consult SynQor applications support (e-mail: [e-mail])
Note 4: Starting up under full load can result in hic-up operation (shut down).
Note 5: Isolation capacitance can be added external to the module (recommended).
