GENERAL DESCRIPTION
The
dc-to-dc regulator. It integrates a 44 mΩ high-side power MOSFET
and a low-side driver to provide a high efficiency solution. The
ADP2380
deliver 4 A of output current. The output voltage can be adjusted
to 0.6 V to 90% of the input voltage. The switching frequency of
the
fixed at 290 kHz or 540 kHz. The synchronization function allows
the switching frequency to be synchronized to an external clock
to minimize system noise.
