PM6776：Next generation Intel server CPU digital multiphase controller with PMBus

The PM6776 is a high performance digital dual controller designed to power next generation Intel server CPU processors: all required parameters are programmable through a PMBus^TMinterface.

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 PM6776 device features up to 6 + 1 phase programmable operation. The PM6776 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 a VFQFPN48 6 x 6 mm package.
