Hot-selling and scarce ADP3205J Multiphase IMVP-IV Core Controller for Mobile CPUs QFN40 spot stock

Product Descriptions

The ADP3205 is a 1-, 2-, or 3-phase hysteretic peak current modedc-to-dc buck converter controller dedicated to powering a mobileprocessor’s core . The chip optimized low voltage design runs fromthe 3.3 V system supply .The chip contains a precision 6-bit DACwhose nominal output voltage is set by VID code .The ADP3205features high speed operation to allow a minimized inductor sizethat 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 ADOPToptimal 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 .TheADP3205 is capable of providing synchronous rectification controlto extend battery lifetime in light load conditions .

The ADP3205 is specified over the extended commercial temperaturerange of 0°C to 100°C and is available in a 40-lead LFCSP package .
