Update: 29 September, 2023
The ISL6324A dual PWM controller delivers high efficiency and tight regulation from two synchronous buck DC/DC converters. The ISL6324A 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 ISL6324A 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 2-to-4-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 integrated driver provides a second precision voltage regulation system for the North Bridge portion of the processor. This monolithic, dual controller with integrated driver solution provides a cost and space saving power management solution. For applications which benefit from load line programming to reduce bulk output capacitors, the ISL6324A features output voltage droop. The multi-phase portion also includes advanced control loop features for optimal transient response to load application and removal
