DESCRIPTION
The MP2886A is a digital, multi-phase, pulsewidth 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 powerloop 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.
