The PM6764TR is a high +performance digital controller designed to power Intel’s VR12.5 processors and memories. + +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 PM6764TR device features up to 4-phase programmable operation. + +The PM6764TR 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. -- cgit v1.2.3
