GENERAL DESCRIPTION
The ADP3205 is a 1-, 2-, or 3-phase hysteretic peak current mode
dc-to-dc buck converter controller dedicated to powering a mobile
processor’s core. The chip optimized low voltage design runs from
the 3.3 V system supply. The chip contains a precision 6-bit DAC
whose nominal output voltage is set by VID code. The ADP3205
features high speed operation to allow a minimized inductor size
that results in the fastest possible change of current to the output.
To further minimize the number of output capacitors, the con-
verter features active voltage positioning enhanced with ADOPT
optimal compensation to ensure a superior load transient response.
The output signals interface with ADP3415 MOSFET drivers,
which that are optimized for high speed and high efficiency. The
ADP3205 is capable of providing synchronous rectification control
to extend battery lifetime in light load conditions.
The ADP3205 is specified over the extended commercial temperature
range of 0
°
C to 100
°
C and is available in a 40-lead LFCSP package.
