5 A board description and PCB layout
L6732 5 A demonstration board 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 4.5 V to 14 V and the output voltage is at 3.3 V. The module can deliver an
output current of up to 5 A. The switching frequency is set at 250 kHz (controller free-
running F
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 R15 has been inserted
between High side MOSFET gate and phase pin; R14 has been inserted between low side
MOSFET gate and Pgnd pin.
