Note * : For proper operation the CGDI module requires to install a 22µF chemical or tantalum capacitance accross output terminals.
Note ** : For 9-36V inpt range, the power is derated at 80% at 9V and increases linearly to full power at 12V.
Note*** : The ripple output voltage is the periodic AC component imposed on the output voltage, an aperiodic and random component (noise) has also to be considered. This noise can
be reduced by adding an external capacitor (typically 10nF/rated voltage depending on isolation requirement) connected between the pin Gin and the pin Gout of the converter. This capacitor
should be layed-out as close as possible from the converter.
Note **** : For load regulation characteristics from 0% to full load, please contact factory.
