5A board description
L6725 demoboard realizes in a two 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
5A. The switching frequency is set at 250kHz (controller free-running FBSWB) but it can be set
to 500kHz acting on the EAREF pin. Compared to the 20A version, the only difference of this
board, compared to the first one, is the presence of a dual mosfet chip, for the High-side and
Low-side MOSFETS; besides R13 has been inserted between High side MOSFET Gate and
Phase pin; R15 has been inserted between Low side mosfet Gate and Pgnd pin.
