ISL6366 Datasheet, Description
Dual 6-Phase + 1-Phase PWM Controller for VR12/IMVP7
Applications
ISL6366
The ISL6366 is a dual PWM controller; its 6-phase PWMs control
the microprocessor core or memory voltage regulator, while its
single-phase PWM controls the peripheral voltage regulator for
graphics, system agent, or processor I/O.
The ISL6366 utilizes Intersil’s proprietary Enhanced Active Pulse
Positioning (EAPP) modulation scheme to achieve the extremely
fast transient response with fewer output capacitors.
The ISL6366 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 microprocessor, which sends a PSI# signal to the controller
at low power mode via SVID bus. The controller enters 1- or
2-phase operation in low power mode (PSI1); in the ultra low
power mode (PSI2,3), it can further drop the number of phases
and enable the diode emulation ofthe operational phase.In low
power modes, the magnetic core and switching losses are
significantly reduced, yielding high efficiency at light load. After
the PSI# signal is de-asserted, the dropped phase(s) are added
back to sustain heavy load transient response and efficiency.
Today’s microprocessors require a tightly regulated output voltage
position versus load current (droop). The ISL6366 senses the
output current continuously by measuring thevoltage acrossthe
dedicated current sense resistor or the DCRof the output
inductor. The sensed current flows outof the FB pinto develop the
precision voltage drop across the feedback resistor for droop
control. Currentsensing circuitsalso provide the needed signals
for channel-currentbalancing, average overcurrent protection and
individual phase current limiting. TheTM and TMS pins are to
sense anNTC thermistor’s temperature, which is internally
digitizedfor thermal monitoring and for integrated thermal
compensation of the current sense elements of therespective
regulator.
The ISL6366 features remote voltage sensing and completely
eliminates any potential difference between remote and local
grounds. This improves regulation and protection accuracy. The
threshold-sensitive enable input is available to accurately
coordinate the start-up of the ISL6366 with other voltage rails.
