APPLICATION SUGGESTION
The recommended values of the external components are those shown on the application circuit of fig. 21.
When the supply voltage Vs is less than 10V, a 100
resistor must be connected between pin 2 and pin 3
in order to obtain the maximum output power.
Different values can be used. The following table can help the designer.
