DATASHEET ISL6323A Monolithic Dual PWM Hybrid Controller Powering AMD SVI Split-Plane and PVI Uniplane Processors FN6878 Rev 0.00 Mar 23, 2009 The ISL6323A dual PWM controller delivers high efficiency and tight regulation from two synchronous buck DC/DC converters. The ISL6323A supports hybrid power control of AMD processors which operate from either a 6-.
a multi-phase controller to support uniplane VDD core voltage and a single phase controller to power the Northbridge (VDDNB) in SVI mode. Only the multi-phase controller is active in PVI mode to support uniplane VDD only processors. A precision uniplane core voltage regulation system is provided by a two-to-four-phase PWM voltage regulator (VR) controller. The integration of two power MOSFET drivers, adding flexibility in layout, reduce the number of external components in the multi-phase section. A single phase PWM controller with i.
