The Future of Analog IC Technology
DESCRIPTION
The MP2888A is a digital, multi-phase, pulse-
width modulation (PWM) controller with digital
PWM-VID interface compatible with NVIDIA’s
Open VReg specification. The MP2888A can
work with MPS’s Intelli-Phase products to
complete the multi-phase voltage regulator (VR)
solution with minimal external components. The
MP2888A can be configured with up to 10-
phase operation.
The MP2888A 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 MP2888A can
monitor and report the output current through
the CS output from the Intelli-Phase products.
The MP2888A 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 MP2888A is available in a QFN-40
(5mmx5mm) package.
