3-Phase IMVP-II & IMVP-III Core Controller for Mobile CPUs ADP3204

HYSSET DSHIFT BSHIFT DPRSHIFT BOM DSLP DPRSLP HYSTERESIS SETTING & SHIFT-MUX VR OUT3 PHASE SPLITTER OUT2 OUT1

The or 3-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. The nominal output voltage is set a 5-bit VID code. To accommodate the transition time required by the newest processors for on-the-fly VID changes, 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 ADOPTTM 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.

Notes: 1 All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC) methods. 2 Guaranteed by characterization. 3 Measured from 50% of VID code transition amplitude to the point where VDACOUT settles within ±1% of its steady state value. 4 40 mVPP amplitude impulse with 20 mV overdrive. Measured from the input threshold intercept point 50% of the output voltage swing. 5 Measured between the 30% and 70% points of the output voltage swing. 6 Two test conditions: is OK but forced to fail by applying an out-of-the-CoreGood-window voltage (VCOREFB,BAD V at VVID 1.25 V setting) to the COREFB pin right after the moment that BOM or DPRSLP is asserted/de-asserted. PWRGD should not fail immediately only with the specified blanking delay time. 2) PWRGD is forced to fail (VCOREFB,BAD V at VVID 1.25 V setting) but gets into the CoreGood-window (VCOREFB,GOOD 1.25 V) right after the moment that BOM or DPRSLP is asserted/de-asserted. PWRGD should not go high immediately only with the specified blanking delay time. 7 Measured between DACRAMP and DACOUT pins. 7 Guaranteed by design.
