: from 4.5 V to 14 V
■ Output voltage: 3.3 V
■ Selectable switching frequency: 250 kHz / 500
kHz
■ Overvoltage protection
■ Thermal shut-down
Description
This 4-layer PCB evaluation board implements a
step-down DC-DC converter and demonstrates
the operation of the L6732 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 switching frequency is initially
set at 250 kHz (controller free-running FSW), but
a 500 kHz switching frequency can also be
selected.
