The MP2886A is a digital, multi-phase, pulse-width modulation (PWM) controller with a digital PWM-VID interface that is compatible with NVIDIA’s Open VReg specification. The MP2886A works with MPS’ Intelli-Phase products to complete the multi-phase voltage regulator (VR) solution with minimal external components. The MP2886A can be configured with up to 6-phase operation.
The MP2886A provides an on-chip EEPROM to store and restore device configurations. Device configurations and fault parameters can be easily programmed or monitored via the PMBus/I2C interface. The MP2886A can monitor and report the output current through the CS output from the Intelli-Phase products.
The MP2886A is based on a unique, digital, multi-phase, non-linear control and provides fast transient response to the load transient with minimal output capacitors. With only one power-loop control method for both steady state and load transient, the power loop compensation is very easy to configure.
The MP2886A is available in a QFN-40 (5mmx5mm) package.
