20 A demonstration board
L6728H demonstration board realizes in a four-layer PCB a step-down DC/DC converter
and shows the operation of the device in a general purpose application. The input voltage
can range from 5 V to 12 V buses and the output voltage is fixed at 1.25 V. The application
can deliver an output current up to 30 A. The switching frequency is 300 kHz.
