Multiphase PWM Regulator for AMD Fusion? Mobile
CPUs
ISL6267
The ISL6267 is designed to be completely compliant with AMD
Fusion? specifications. The ISL6267 controls two Voltage
Regulators (VRs), with three integrated gate drivers. The first
VR can be configured as 3-, 2-, or 1-phase VR, while the second
output can be configured as 2- or 1-phase VR, providing
maximum flexibility. The two VRs share the serial control bus
to communicate with the CPU and achieve lower cost and
smaller board area compared with two-chip solutions.
The PWM modulator of the ISL6267 is based on Intersil’s R3
(Robust Ripple Regulator) Technology?. Compared with the
traditional multi-phase buck regulator, the R3 modulator
commands variable switching frequency during load
transients, achieving faster transient response. With the same
modulator, it naturally goes into pulse frequency modulation in
light load conditions, which achieves higher light load
efficiency and extends battery life.
The ISL6267 has several other key features. Both outputs
support DCR current sensing with a single NTC thermostat for
DCR temperature compensation or accurate resistor current
sensing. Both of the outputs utilize remote voltage sense,
adjustable switching frequency, current monitor, OC
protection, independent power-good indicators, temperature
monitors, and a common thermal alert.
