Pratical consideration
3.3.1
Printed circuit board
The layout shown in Figure 14 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.
3.3.2
Assembly suggestion
No electrical isolation is needed between the package and the heatsink with single supply
voltage configuration.
3.3.3
Application suggestions
The recommended values of the components are those shown on application circuit of
Figure 13. However, if different values are chosen then the following table can be helpful.
