FN6599.0
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
www.DataSheaellto4wUs.cothme 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 Technologyhas 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.
