Note * : For proper operation the MGDM-18 module requires to install a 22µF chemical or tantalum capacitance accross output terminals.
Note ** : For 9-36V input range,the current is derated at 80% at 9V and increases linearly to full current 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 see page 4.
