Tri-Loop Digital Multi-Phase Controller with PMBus Interface for IMVP8/9


DESCRIPTION


The MP2949A is a triple-rail, digital, multi-phase controller for the Core/GT/SA rails of both Intel IMVP8 and IMVP9 processor platforms. The MP2949A can work with MPS’s Intelli-Phase products and traditional discrete drivers plus MOSFET structures to complete the multi-phase VR solution with minimum external components. The MP2949A is scalable up to six phases between three separated outputs.
The MP2949A provides an on-chip multiple-time programmer (MTP) to store and restore device configurations. Device configurations and fault parameters can be programmed or monitored easily using the PMBus interface. The MP2949A can monitor and report output current through the CS output from either Intelli-Phase products or the MPS driver.
The MP2949A is based on a unique, digital, multi-phase, non-linear control to provide fast transient response to a load step with a minimal number of output capacitors. With only one power loop control method for both the steady state and load transient, power loop compensation is very easy to configure without back-and-forth testing and adjusting.
The MP2949A also provides active current balancing and auto-phase shedding for better thermal and efficiency performance. The MP2949A includes input and output voltage, power (PSYS), output current (IMON), temperature monitoring with selectable protection functions, and programmable load line for each rail.
The MP2949A is available in an RoHS compliant QFN-48 (6mmx6mm) package.
