Description

This 4-layer PCB demonstration board is

designed as a step-down DC-DC converter to

demonstrate the operation of the L6725 device in

a general-purpose application. The input voltage

can range from 4.5 V to 14 V with an output

voltage of 3.3 V. The module can deliver an output

current in excess of 20 A. The L6725 device can

100 ns. This makes possible conversions with

very low duty cycles and very high switching

frequencies. The switching frequency is initially

set at 250 kHz (controller free-running FSW), but

a switching frequency of 500 kHz can also be

selected.
