MP2949A
Tri-Loop Digital Multi-Phase Controller
with PMBus Interface for IMVP8/9
DESCRIPTION
FEATURES
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.
Up to 6-Phase Triple-Rail Digital PWM
Controller
Configurable Phase Number: 3+2+1,
4+1+1, 2+1+1, 1+1+1, etc.
Intel’s IMVP8 and IMVP9 Compliant
PMBus Compliant for Programming and
Monitoring
Serial VID Interface
Built-In MTP to Store Customer
Configuration
Automatic Loop Compensation
Fewer External Components than
Conventional Analog Controller
Auto-Phase Shedding to Improve Overall
Efficiency
Phase-to-Phase Active Current Balancing
Input and Output Voltage and Power,
Output Current Monitoring
Regulator Temperature Monitoring
UVLO/OVP/UVP/OCP/OTP/RVP with No
Action, Latch, Retry, or Hiccup Options
Digital Programmable Load Line
Available in a QFN-48 (6mmx6mm)
Package
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.
APPLICATIONS
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),
