GENERAL DESCRIPTION

The ADP3203 is a 1 or 2-phase hysteretic peak current

DC-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^TM

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

efficiency 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.
