SPECIAL RECOMMENDATIONS
As stated in the error amplifier section, a capacitor
of 10 nF (minimum value: 8 nF) should always be
connected to the COMP pin to insure a correct
stability of the internal error amplifier. This is
represented on figures 14, 15 and 18.
In order to improve the ruggedness of the device
versus eventual drain overvoltages, a resistance of
1 kΩ should be inserted in series with the TOVL
pin, as shown on figures 14 and 15. Note that this
resistance doesn’t impact the overload delay, as its
value is negligible in front of the internal pull up
resistance (about 125 kΩ).
SOFTWARE IMPLEMENTATION
All the above considerations and some others are
included in a design software which provides all
the needed components around the VIPer device
for a specified output configuration. This software
is available in download on the ST internet site.
