Note * : These performances are measured with the sense line connected..
Note ** : It is recommended to mount the converter on a heatsink for this test, see section 10-3 and 10-9 for further details.
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 4 external decoupling capacitors connected between inputs and case and between outputs and case. These capacitance should
be layed-out as close as possible from the converter. Please refer to page 8 for more details.
