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.
