20 A demonstration board

The L6728D demonstration board is constructed using a four-layer PCB, and is designed as

a step-down DC-DC converter. The board demonstrates 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.
