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 device 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 device is available in
VFQFPN28 4 x 4 mm (PM6764) and VFQFPN40
5 x 5 mm (PM6766) packages.
