ISL6364CRZ : Dual 4-Phase + 1-Phase PWM Controller for VR12/IMVP7 Applications
The ISL6364 is a dual PWM controller; its 4-phase PWMs control the microprocessor core or the memory voltage regulator, while its single-phase PWM controls the ( ISL6364CRZ ) peripheral voltage regulator for graphics, system agent, or processor I/O
The ISL6364 is designed to be compliant to Intel VR12/IMVP7 specifications. It accurately monitors the load current via the IMON pin and reports this information via the IOUT register to the ( ISL6364CRZ ) microprocessor, which sends a PSI# signal to the ( ISL6364CRZ ) controller at low power mode via SVID bus. The controller enters 1- or 2-phase operation ( ISL6364CRZ ) in low power mode (PSI1); in the ultra low power mode (PSI2,3), it can further drop the number of phases
and then enable the diode emulation of the ( ISL6364CRZ ) operational phase. In low power modes, the magnetic core and switching losses ( ISL6364CRZ ) are significantly reduced, yielding high efficiency at light load. After the PSI# signal is de-asserted, the dropped phase(s) are ( ISL6364CRZ ) added back to sustain heavy load transient response and efficiency
The ISL6364 features remote voltage sensing and ( ISL6364CRZ ) completely eliminates any potential difference between remote and local ( ISL6364CRZ ) grounds. This improves regulati on and protection accuracy. The threshold-sensitive enable input is available to accurately ( ISL6364CRZ ) coordinate the start-up of the ISL6364 with other voltage rails.
