5A demonstration board
L6728A 5 A demonstration board realizes, in a two-layer PCB, a step-down DC/DC
converter and shows the operation of the device in a general-purpose high-current
application. Different output voltage rails have been considered: 8 V, 5 V, 3.3 V, 2.5 V, 1.25 V
and 0.8 V. The input voltage can range from a bottom value that depends on the chosen rail
up to 15 V buses (absolute maximum). The application can deliver an output current up to
the value fixed by R
