MP2856
Monolithic Power Systems
Dual-Loop, Digital, Multi-Phase Controller with a PMBus Interface for AMD SVI3
Package Type: TQFN-40, 5mmx5mm
We can program the controller according to your video card. After selecting the "Firmware" option please write the exact model of your device before completing the payment !
The MP2856 is a dual-loop, digital, multi-phase
controller that provides power to the core of the
AMD SVI3 platform.
The MP2856 can work with MPS’s Intelli-
PhaseTM products to complete the multi-phase
voltage regulator (VR) solution with minimal
external components. The MP2856 can be
configured for up to 8-phase operation on rail 1
and up to 4-phase operation on rail 2.
The MP2856 provides an on-chip non-volatile
memory (NVM) to store and restore device
configurations. Device configurations and fault
parameters can be easily configured or
monitored via the PMBus/I2C interface. The
MP2856 can monitor and report the output
current (IOUT) through the Intelli-PhaseTM current-
sense (CS) output.
The MP2856 is based on unique, digital, multi-
phase nonlinear control to provide fast transient
response to the load transient with minimal
output capacitors. With only one power loop
control method for both the steady state and load
transient, power loop compensation is simple to
configure.
The MP2856 is available in a TQFN-40
(5mmx5mm) package.
