APPLICATION SUGGESTION
The recommendedvalues of theexternal componentsarethoseshown on the applicationcircuit of fig.21.
When the supply voltageV
s
is less than 10V, a100
resistor mustbe connected betweenpin 2 and pin 3
in orderto obtain the maximumoutput power.
Differentvalues can be used. The followingtable can help the designer.
