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.
