ISL6265CHRTZ-T Datasheet

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


The ISL6265C 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 ISL6265C 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 ISL6265C can be configured as independent single-phase controllers powering VDD0 and VDD1.
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.
