Dual PWM Controller For Powering AMD SVI Split-Plane Processors

The ISL6328 dual PWM controller delivers high efficiency and tight regulation from two synchronous buck DC/DC converters. The ISL6328 supports power control of AMD processors, which operate from a serial VID interface SVI. The dual output ISL6328 features a multi-phase controller to support the Core voltage VDD and a single phase controller to power the Northbridge VDDNB.
