20A board description
L6725 demoboard 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 4.5V
to 14V and the output voltage is at 3.3V. The module can deliver an output current in excess of
20A. The switching frequency is set at 250kHz (controller free-running FBSWB) but it can be
set to 500kHz acting on the EAREF pin.
