MP2932GQK-LF-Z

Overview

The MP2932GQK-LF-Z is a 6-phase PWM controller designed for VR10 and VR11 processor core voltage regulation. It features dual-loop digital control with an integrated PMBus interface, supporting AVSBus communication. The device operates within a wide input voltage range and utilizes a QFN-48 (6mmx6mm) package. Key electrical parameters include a maximum switching frequency of 3MHz, support for 3-bit PVID modes, and programmable phase counts ranging from 2 to 6 phases per channel. It incorporates built-in EEPROM for configuration storage and supports nonlinear control to minimize output overshoot.

Feature Summary

• Dual-loop digital multi-phase architecture with automatic loop compensation and flexible phase allocation
• Integrated PMBus interface with I2C compatibility and AVSBus support for dynamic voltage scaling
• Nonlinear control mechanism that reduces output voltage overshoot during transient load changes
• Built-in EEPROM for storing personalized configurations and recording Intelli-Phase MOSFET fault types

Applications

• Microprocessor core voltage regulation for VR10 and VR11 standards
• VR13.HC compatible power delivery systems
• AVSBus enabled processor power management applications

Procurement Notes

Verify the specific suffix LF-Z against the manufacturer's current datasheet to confirm lead-free compliance and packaging details. Confirm availability status as production status may vary by region. Ensure the ordering part number matches the exact pinout and thermal requirements for the target PCB design before finalizing procurement.

Selection Notes

Select this component when designing for VR10/VR11 processors requiring precise current balancing and fast transient response. The digital control allows for reduced external component count compared to analog controllers. Consider the 3MHz switching capability for smaller passive sizes. Verify compatibility with the target processor's VID codes and PMBus address requirements.

Part Context

This component belongs to the MP29xx series of professional power management ICs from Monolithic Power Systems. It serves as a successor or alternative to older analog controllers in high-performance computing platforms. The device integrates advanced digital features typically found in discrete solutions into a single compact QFN package, simplifying board layout and improving system reliability.

Replacement Considerations

MP2965 is listed as an alternative for new designs, offering VR13.HC and AVSBus compatibility. Verify pin-to-pin compatibility and software configuration migration if replacing existing MP2932 designs.
