PRACTICAL CONSIDERATIONS
Printed circuit board
The layout shown in Fig. 16 should be adopted by
the designers. If different layouts are used, the
ground points of input 1 and input 2 must be well
decoupled from the ground return of the output in
which a high current flows.
Assembly suggestion
No electrical isolation is needed between the
package and the heatsink with single supply voltage
configuration.
Application suggestions
The recommended values of the components are
those shown on application circuit of fig. 13.
Different values can be used. The following table
can help the designer.
