Product overview

Description

The PM6780 is a high performance dual digital loop controller designed to power next-generation high performance microprocessors: it can be configured to work with Intel’s VR14 or AVS compliant microprocessors. All the required parameters are programmable through the 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 PM6780 can support up to 8 phases on a single rail (4+4 in dual rail) and allows programmable phase assignment between the two loops.

The PM6780 supports 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 5x5mm compatible with common footprint directions.
