Multiphase PWM Regulator for AMD Fusion? Desktop CPUs
Using SVI 2.0
ISL62773
The ISL62773 is fully compliant with AMD Fusion? SVI 2.0 and
provides a complete solution for desktop microprocessor and
graphics processor core power. The ISL62773 controller supports
two Voltage Regulators (VRs) with three integrated gate drivers
and two optional external drivers for maximum flexibility. The
Core VR can be configured for 3-, 2-, or 1-phase operation while
the Northbridge VR supports 2- or 1-phase configurations. 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 ISL62773 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.
