GENERAL DESCRIPTION  
The ADP3422 is a hysteretic dc-dc buck converter controller to  
power a mobile processor’s core. The optimized low voltage  
design is powered from the 3.3 V system supply. The 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 ADP3422 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 ADP3422 features active  
voltage positioning that can be optimally compensated 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 upper and lower  
(synchronous) MOSFETs of the buck converter.
