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 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 1 external decoupling capacitor connected between Gin and Gout. These capacitance should be layed-out as close as possible from
the converter. The ripple output voltage is measured by connecting a ceramic chip capacitor Co accross Vo and Go pins (C=100µF if Vo<5Vdc C=10µF if Vo>5Vdc).
Note **** : From 50V to 100V input voltage a minimum load of 20W is required otherwise the converter will fall in hicuup mode for put voltag equal or below 5Vdc.
