ADP3204 Descrizione generale

GENERAL DESCRIPTIONThe ADP3204 is a 1-, 2-, or 3-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. The nominal output voltage is set by a 5-bit VID code. To accommodate the transition time required by the newest processors, the ADP3204 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 ADP3204 features active voltage positioning with ADOPT optimal compensation to ensure a superior load transient response. The output signals interface with a maximum of three ADP3415 MOSFET drivers that are optimized for high speed and high efficiency for driving both the top and bottom MOSFETs of the buck converter. The ADP3204 is capable of controlling the synchronous rectifiers to extend battery lifetime in light load conditions.FEATURES Pin Selectable 1-, 2-, or 3-Phase Operation Static and Dynamic Current Sharing Characteristics Backward Compatible to IMVP-II Superior Load Transient Response with ADOPT® Analog Devices’ Optimal Positioning Technology Noise-Blanking for Speed and Stability Synchronous Rectifier Control Extends Battery Life Smooth Output Transition During VID Code Change Cycle-by-Cycle Current Limiting Hiccup or Latched Overload Protection Transient-Glitch-Free Power Good Soft Start Eliminates Power-On In-Rush Current Surge Two-Level Overvoltage and Reverse Voltage ProtectionAPPLICATIONS IMVP-II and IMVP-III Core DC-to-DC Converters Fixed Voltage Mobile CPU Core DC-to-DC Converters Notebook/Laptop Power Supplies Programmable Output Power Supplies
