Special recommendations
As steted in the error amplifier section, a capacitor of 10nF capacitor (minimum value: 8nF)
should always be connected to the COMP pin to ensure correct stability of the internal error
amplifier
In order to improve the ruggedness of the device versus eventual drain overvoltages, a
resistance of 1k should be inserted in series with the TOVL pin, as shown on
Figure 19 on page
Note that, this resistance does not impact the overload delay, as its value is negligible prior
to the internal pull-up resistance (about 125k ).
Software implementation
All the above considerations and some others are included included in ST design software
which provides all of the needed components around the VIPer device for specified output
configurations, and is available on
