1 / 42 page  MP2935 4-Phase PWM Controller for VR12.5 Applications MP2935 Rev. 1.02 www.MonolithicPower.com 1 8/25/2015 MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2015 MPS. All Rights Reserved. The Future of Analog IC Technology DESCRIPTION MP2935 is a high-efficiency, 4-phase, synchronous, buck-switching PWM controller with an SVID interface for high-performance Intel processors. The multi-phase PWM output signals can be configured for up to 4-phase operation with interleaved switching. MP2935 adopts three-logic-level PWM outputs for enhanced noise immunity and flexible fault management. Depending on the power states set by SVID command, the multi-phase channel can switch between multiphase and single- phase operation. In addition, MP2935 supports programmable load-line resistance. As a result, the output voltage is always optimally positioned for a load transient. The chip also provides accurate and reliable short-circuit protection with adjustable current limit threshold and a delayed VR_RDY output that is masked during on-the-fly output voltage changes to eliminate false triggering. MP2935 performance is specified over the junction temperature range of -10°C to 125°C. The chip is available in 40-lead QFN package. FEATURES VR12.5 compliant Multi-Phase Operation at up to 2MHz per Phase Tri-State PWM Outputs for Driving MPS Intelli-PhaseTM Devices Power-Saving Modes Maximize Efficiency During Light Load and Deeper-Sleep Operation Active Current Balancing between Output Phases Independent Current Limit and Load Line Setting Inputs for Additional Design Flexibility 8-bit Digitally Programmable 0V to 3.04V Output through Serial VID Interface Overload and Short-Circuit Protection with Latch-Off Delay Output Current Monitor Fault Latch Output Regulator Temperature Monitor Available in a 6mmx6mm 40-lead QFN package APPLICATIONS Power supplies for next-generation Intel® processors All MPS parts are lead-free, halogen free, and adhere to the RoHS directive.
