Figure 16. Offset Trimming
Because of the tolerance of the output voltage, it is not possible to delete completely the effect of the offset
on CGA pin on all the allowed output voltage range: if the trimming operation is performed at VOUT(MIN),
then on pin CGA the maximum residual voltage will be present at VOUT(MAX) and its value will be:
To simplify the procedure, the following step-by step process can be used:
s
a trimmer has to be placed between sense pins of each section: the value of the trimmer resistance
must be at least one order of magnitude higher than RG and it has to be set at one half of its range
(
δ=0.5);
s
once the application is running at a load defined by the designer based on the required sharing
accuracy, the master section has to be located;
s
on the slave sections it is then necessary to operate on the trimmer to make equal the output currents.
