Overview
DATASHEET ISL6323B Monolithic Dual PWM Hybrid Controller Powering AMD SVI Split-Plane and PVI Uniplane Processors FN6879 Rev 0.
00 Mar 23, 2009 The ISL6323B dual PWM controller delivers high efficiency and tight regulation from two synchronous buck DC/DC converters.
The ISL6323B supports hybrid power control of AMD processors which operate from either a 6-bit parallel VID interface (PVI) or a serial VID interface (SVI).
The dual output ISL6323B features 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...
