ISL6328A
Dual PWM Controller For Powering AMD SVI Split-Plane Processors
FN7986 Rev 1.
00 February 13, 2015
The ISL6328A dual PWM controller delivers high efficiency and tight regulation from two synchronous buck DC/DC converters.
The ISL6328A supports power control of AMD processors, which operate from a serial VID interface (SVI).
The dual output ISL6328A 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-four-phase PWM voltage
regulator (VR) controller.
The integration of two power MOSFET drivers adds flexibility in layout and reduc...
