Two-Phase Core Controller for AMD
Mobile Turion CPUs
The ISL6264 is a two-phase buck controller with embedded
gate drivers. The two-phase buck controller uses two
interleaved 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 real estate area.
ISL6264 can also be configured as single-phase controller
for low power CPU applications.
Features
? Precision Two-phase Core Voltage Regulator
- 0.5% System Accuracy Over-temperature
? Voltage Positioning with Adjustable Load Line and Offset
? Internal Gate Driver with 2A Driving Capability
? Dynamic Phase Adding/Dropping
? Differential Current Sensing: DCR or Resistor
? Microprocessor Voltage Identification Input
The heart of the ISL6264 is the patented
R 3
Technology ? ,
- 6-Bit VID Input
Intersil’s Robust Ripple Regulator modulator. Compared with
the traditional multi-phase buck regulator, the R 3
Technology ? has the fastest transient response. This is due
to the R 3 modulator commanding variable switching
frequency during a load transient.
To boost battery life, the ISL6264 supports PSI_L for deeper
sleep mode via automatically enabling different operation
modes. At heavy load operation of the active mode, the
regulator commands the two phase continuous conduction
mode (CCM) operation. While the PSI_L is asserted during
the deeper sleep mode, the ISL6264 smoothly disables one
phase and operates in a one-phase diode emulation mode
- 0.775V to 1.55V in 25mV Steps
- 0.375V to 0.7625V in 12.5mV Steps
? Adjustable Reference-Voltage Offset
? Audio Filter Enable/Disable
? User Programmable Switching Frequency
? Differential Remote CPU Die Voltage Sensing
? Static and Dynamic Current Sharing
? Overvoltage, Undervoltage, and Overcurrent Protection
? Pb-Free (RoHS Compliant)
(DE) to maximize the efficiency at light load.
A 6-bit digital-to-analog converter (DAC) allows dynamic
adjustment of the core output voltage from 0.375V to 1.55V.
A 0.5% system accuracy of the core output voltage over
temperature at active mode is achieved by the ISL6264.
A unity-gain differential amplifier is provided for remote CPU

die sensing. This allows the voltage on the CPU die to be
accurately measured and regulated per AMD mobile CPU
specifications. Current sensing can be realized using either
lossless inductor DCR sensing or precision resistor sensing.
A single NTC thermistor network thermally compensates the
gain and the time constant of the DCR variations.
