Description
The PM6764/66 is a high performance digital
controller designed to power Intel’s VR12.5
processors (PM6766) and memories (PM6764):
all required parameters are programmable
through a PMBus™ interface.
The device utilizes digital technology to
implement all control and power management
functions to provide maximum flexibility and
performance. The NVM is embedded to store
custom configurations.
The PM6764/66 features up to 4/6-phase
programmable operation. The PM6764/66
supports power state transitions featuring VFDE,
and programmable DPM maintaining the best
efficiency over all loading conditions without
compromising transient response. The device
assures fast and independent protection against
load overcurrent, under/overvoltage and feedback
disconnections. The devices are available in
VFQFPN28 4 x 4 mm (PM6764) and VFQFPN40
5 x 5 mm (PM6766) packages.

I/O Type
Function
Channel 5 current sense positive input.
I
Analog
Connect through an R-C filter to the phase-side of the channel
5 inductor.
When working at < 5-phase, short to the regulated voltage.
Channel 5 current sense negative input.
I Analog Connect to the output-side of the channel 5 inductor. Filter with
100 nF (typ.) to GND.
Channel 6 current sense negative input.
I Analog Connect to the output-side of the channel 6 inductor. Filter with
100 nF (typ.) to GND.
Channel 6 current sense positive input.
I
Analog
Connect through an R-C filter to the phase-side of the channel
6 inductor.
When working at < 6-phase, short to the regulated voltage.
Enable driver.
CMOS output driven high when the IC commands the drivers.
O CMOS Used in conjunction with the HiZ window on the PWMx pins to
optimize the overall efficiency. Connect directly to the external
driver enable pin.
O Tristate
O Tristate PWM output.
O Tristate Connect to related external driver PWM input.
During normal operations the device is able to manage HiZ
O Tristate status by setting and holding the PWMx pin to fixed voltage
O Tristate defined before.
O Tristate
VR ready.
O
Open
drain
Set free after SS has finished and pulled low when triggering
any protection.
Pull-up to an external voltage equal or lower than VCC5.
If not used it can be left floating.
O
Open VR12.5 bus alert. Pull-up to an external voltage equal or lower
drain than VREF_1V8.
Voltage regulator HOT.
This is an alarm signal asserted by the controller when the
O
Open temperature sensed through the TM pin exceeds TMAX (active
drain low).
Pull-up to an external voltage equal or lower than VCC5.
See Section 5.5.1 on page 27 for details.
GND connection.
All internal references and logic are referenced to this pin. Filter
to VCC5 and VREF_1V8 with the proper MLCC capacitor and
connect to the PCB GND plane.
