Multiphase PWM Regulator for AMD Fusion? Mobile CPUs
Using SVI 2.0
ISL62771
The ISL62771 is fully compliant with AMD Fusion? SVI 2.0 and
provides a complete solution for microprocessor and graphics
processor core power. The ISL62771 controller supports two
Voltage Regulators (VRs) with three integrated gate drivers. The
Core VR supports 2-, or 1-phase configurations while the
Northbridge VR supports 1-phase operation. The two VRs share a
serial control bus to communicate with the AMD CPU and achieve
lower cost and smaller board area compared with two-chip
solutions.
The PWM modulator is based on Intersil’s Robust Ripple
Regulator (R3) Technology?. Compared to traditional modulators,
the R3 modulator can automatically change switching frequency
for faster transient settling time during load transients and
improved light load efficiency.
The ISL62771 has several other key features. Both outputs
support DCR current sensing with single NTC thermistor for
DCR temperature compensation or accurate resistor current
sensing. Both outputs utilize remote voltage sense, adjustable
switching frequency, OC protection and power-good.
