GENERAL DESCRIPTION

DACOUT

AND

The ADP3203 is a 1- or 2-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 and draws only 10 µA maximum

in shutdown. The nominal output voltage is set by a 5-bit VID

code. To accommodate the transition time required by the

newest processors for on-the-fly VID changes, the ADP3203

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 ADP3203 features active voltage positioning with

ADOPT optimal compensation to ensure a superior load transient

response. The output signal interfaces with the ADP3415

MOSFET driver that is optimized for high speed and high effi-

ciency for driving both the top and bottom MOSFETs of the buck

converter. The ADP3203 is capable of controlling the synchronous

rectifier to extend battery lifetime in light load conditions.
