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

Ω 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 k

Ω).

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.
