Multi-Output Controller with Integrated MOSFET Drivers for AMD SVI Capable Mobile CPUs

The ISL6265 is a multi-output controller with embedded gate drivers. A single-phase controller powers the Northbridge (VDDNB) portion of the CPU. The two remaining controller channels can be configured for two-phase or individual single-phase outputs. For uniplane CPU applications, the ISL6265 is configured as a two-phase buck converter.
