GENERAL DESCRIPTION
The ADP3204 is a 1-, 2-, or 3-phase hysteretic peak current
dc-to-dc buck converter controller dedicated to power a mobile
processor’s core. The optimized low voltage design is powered
from the 3.3 V system supply. The nominal output voltage is
set by a 5-bit VID code. To accommodate the transition time
required by the newest processors, the ADP3204 features
high speed operation to allow a minimized inductor size that
results in the fastest change of current to the output. To
further allow for the minimum number of output capacitors
to be used, the ADP3204 features active voltage positioning
with ADOPT
optimal compensation to ensure a superior
load transient response. The output signals interface with a
maximum of three ADP3415 MOSFET drivers that are
optimized for high speed and high efficiency for driving both the
top and bottom MOSFETs of the buck converter. The
ADP3204 is capable of controlling the synchronous rectifiers to
extend battery lifetime in light load conditions.
