Multi-Output Controller with Integrated MOSFET Drivers
for AMD SVI Capable Mobile CPUs
ISL6265C
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.
The heart of the ISL6265C 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.
