Multi-Output Controller with Integrated
MOSFET Drivers for AMD SVI Capable
Mobile CPUs
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 components, lower component 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 R 3 Technology?,
Intersil’s Robust Ripple Regulator modulator. Compared with
the traditional buck regulator, the R 3 Technology ? has a
faster transient response. This is due to the R 3 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.
