INTERSIL ISL6265HRTZ ISL6265 QFN 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. This allows the controller to interleave channels to effectively double the output voltage ripple frequency and thereby reduce output voltage ripple amplitude with fewer components, lower component cost, reduced power dissipation, and smaller area. For dual-plane processors, the ISL6265 can be configured as independent single-phase controllers powering VDD0 and VDD1.

The heart of the ISL6265 is the patented R³ Technology™, Intersil's Robust Ripple Regulator modulator. Compared with the traditional buck regulator, the R³ Technology™ has a faster transient response. This is due to the R³ modulator commanding variable switching frequency during a load transient.

The Serial VID Interface (SVI) allows dynamic adjustment of the Core and Northbridge output voltages independently and in combination from 0.500V to 1.55V. Core and Northbridge output voltages achieve a 0.5% system accuracy over-temperature.

A unity-gain differential amplifier is provided for remote CPU die sensing. This allows the voltage on the CPU die to be accurately regulated per AMD mobile CPU specifications. Core output current sensing is realized using lossless inductor DCR sensing. All outputs feature overcurrent, overvoltage and undervoltage protection.
