MP2935DQK-LF-Z

Overview

The MP2935DQK-LF-Z is a four-phase synchronous buck PWM controller designed for VR12.5 applications, primarily targeting high-performance Intel processors. It features an SVID interface and supports up to 2MHz switching frequency per phase. The device includes programmable Load-Line adjustment, Intelli-Phase MOSFET fault detection, and comprehensive protection mechanisms such as UVLO, OVP, UVP, OCP, and OTP. It operates within a junction temperature range of -10°C to 125°C and utilizes a 40-lead QFN package.

Feature Summary

• Supports multi-phase operation with flexible phase allocation and automatic interleaving for optimized efficiency across load ranges.
• Integrates intelligent fault management including Intelli-Phase MOSFET fault detection and recording capabilities.
• Provides adjustable Load-Line resistance to maintain optimal output voltage during transient load changes.

Applications

• High-performance Intel processor power delivery
• VR12.5 compliant system designs
• Multi-phase synchronous buck converter topologies

Procurement Notes

Verify the specific suffix DQK against official MPS documentation to confirm pinout and thermal pad configuration. Confirm current production status as the base MP2935 model may have limited availability for new designs. Ensure compatibility with required SVID protocol versions and check for any recommended alternative part numbers for new development projects.

Selection Notes

Select this component for designs requiring precise current sharing and thermal balancing between phases. Consider the integrated fault detection and EEPROM storage if design flexibility and post-production configuration adjustments are necessary. Evaluate the 40-lead QFN package constraints regarding PCB layout and thermal dissipation requirements for the target application environment.
