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.PM6764: 4-phase compact digital controllerPM6766: 6-phase compact digital controllerVR12.5™ compliant with 25 MHz SVID bus rev. 1.2, serial-VID with programmable IMAX, TMAX, VBOOT, ADDRESSHigh-performance digital control loop (digital STVCOT™)Fully configurable through PMBus™Flexible driver/DrMOS supportSingle NTC design for TM, LL and IMON thermal compensationDPM - dynamic phase managementRemote sense; 0.5% Vout accuracy with calibrationCurrent sense across DCR with calibrationAutocalibration capability for current and voltage senseProgrammable voltage positioningOV, UV and FB disconnection protectionEmbedded non-volatile memory (NVM)Black box recorderPM6764: VFQFPN28 4 x 4 mm packagePM6766: VFQFPN40 5 x 5 mm package
