ISL6329 - Dual PWM Controller Powering AMD SVI Split-Plane Processor

Key Features

  • a multiphase controller to support the Core voltage (VDD) and a single phase controller to power the Northbridge (VDDNB). A precision core voltage regulation system is provided by a one-to-six-phase PWM voltage regulator (VR) controller. The integration of two power MOSFET drivers adds flexibility in layout and reduces the number of external components in the multi-phase section. A single phase PWM controller with integrated driver provides a second precision voltage regulation system for the No.

DATASHEET ISL6329 Dual PWM Controller Powering AMD SVI Split-Plane Processors FN7800 Rev 0.00 April 19, 2011 The ISL6329 dual PWM controller delivers high efficiency and tight regulation from two synchronous buck DC/DC converters. The ISL6329 supports power control of AMD processors, which operate from a serial VID interface (SVI). The dual output ISL6329 features a multiphase controller to support the Core voltage (VDD) and a single phase controller to power the Northbridge (VDDNB). A precision core voltage regulation system is provided by a one-to-six-phase PWM voltage regulator (VR) controller. The integration of two power MOSFET drivers adds flexibility in layout and reduces the number of external components in the multi-phase section.
