Product overview

Description

The PM6779 is a high performance dual digital loop controller designed to power Intel’s VR13.HC processors: all required parameters are programmable through PMBus™ interface.

The device utilizes digital technology to implement all control and power management functions to provide maximum flexibility and performance. NVM is embedded to store custom configurations.

The PM6779 can support up to 8 phases and allows programmable phase assignment between the two loops.

The PM6779 supports Power State transitions featuring Pulse Skipping, 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 VFQFPN40 5x5 mm.
