Description
L6730 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 4.5 V to 14 V and the output voltage is at 3.3 V. The module can deliver an
output current in excess of 30 A. The switching frequency is set at 400 kHz (controller free-
running FSW) but it can be increased up to 1 MHz. A 7 positions dip-switch allows to select
the UVLO threshold (5 V or 12 V bus), the OVP intervention mode and the sink-mode
current capability.
