PM6773

Overview

The PM6773 is a 12 V input, dual-channel, multi-phase digital controller designed for data center power delivery. It supports 3+1 phase operation and complies with Intel VR12, VR12.5, and VR13 standards. The device features embedded non-volatile memory (NVM) for configuration storage and a black-box recorder. It utilizes the PMBus interface for programmability and telemetry reporting of voltage, current, power, temperature, and fault status. Available in VFQFPN48 6x6 mm packages.

Feature Summary

• Complies with Intel server VR12, VR12.5, and VR13 standards
• Features embedded non-volatile memory for configuration and black-box recording
• Provides full configurability via PMBus communication interface
• Supports telemetry output for key power parameters

Applications

• Intel CPU power supply
• DDR memory power supply
• VCCIO/VMCP power supply

Procurement Notes

Verify package type availability as the PM6773 is specified in VFQFPN48 6x6 mm. Confirm compliance with required Intel VR specifications during design-in. Ensure PMBus interface compatibility with system management controllers. Check for updated revisions against legacy VR12 or VR12.5 requirements if applicable to the target platform.

Selection Notes

Select this component for applications requiring strict adherence to Intel server VR standards. The integrated NVM simplifies deployment by storing custom configurations locally. Consider the 6x6 mm footprint for space-constrained PCB layouts. Evaluate the need for black-box logging capabilities for system diagnostics and fault analysis.

Part Context

Part of STMicroelectronics' digital multiphase controller portfolio for high-performance computing. Designed to meet the stringent power delivery requirements of modern processors and memory architectures in data center environments.

Replacement Considerations

PM6776: Supports 6+1 phases in similar packaging. PM6779: Supports VR13.HC with up to 8 phases in VFQFPN40.
