The ISL6265A 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 ISL6265A is configured as a two-phase buck converter. This allows the controller to interleave channels to effectively double the output voltage ripple frequency, and thereby reduce output voltage ripple amplitude with fewer ponents, lower ponent cost, reduced power dissipation, and smaller area. For dual-plane processors, the ISL6265A can be configured as independent single-phase controllers powering VDD0 and VDD1.
The heart of the ISL6265A is the patented R3 Technology™, Intersil’s Robust Ripple Regulator modulator. pared with the traditional buck...
