Description
The MP2869A is a dual-rail, digital, multi-phase controller that provides power for AMD SVI3 core power. The device can work with MPS’s Intelli-PhaseTM products to complete the multi-phase voltage regulator (VR) solution with minimal external components. The MP2869A can be configured to maximum 16-phase operation for rail 1, and maximum 8-phase operation for rail 2.
The MP2869A 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 device can monitor and report the output current (IOUT) via the current-sensing output of the Intelli-PhaseTM devices.
The MP2869A is based on a unique, digital, multi-phase, nonlinear control to provide fast transient response to load transients with minimal output capacitors. With only one power-loop control method for steady state and load transients, power loop compensation is very easy to configure.
The MP2869A is available in a TQFN-56 (7mmx7mm) package.

MEETING THE IMPEDANCE MASK: STRATEGIES FOR PDN DESIGN AND OPTIMIZATIONARTICLEIn telecommunication applications, target impedance serves as a crucial benchmark for PDN design. It ensures that the die operates within an acceptable level of rail voltage noise, even under the worst-case transient current scenarios, by defining the maximum allowable PDN impedance for the power rail on the die. This article will focus on the optimization techniques to meet the target impedance ...
