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 converter 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.
