PCB layout

Figure 38 and Figure 39 show the layout of the PCB.

The demonstration board has been designed to fit in a typical LED driver case so the

maximum height is 20 mm, maximum length is 90 mm and the maximum width is less than

65 mm.

Of course the form factor could be further reduced depending on the capacitor value. Here a

very narrow current ripple has been defined as a specification, but accepting a higher value,

the capacitor size could be further reduced.
