ISL6267

Multiphase PWM Regulator for AMD Fusion™ Mobile CPUs

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.
