Description
The MP2886A is a digital, multi-phase, pulse-width modulation (PWM) controller with a digital PWM-VID interface that is compatible with Open VReg specification. The MP2886A works with MPS’s Intelli-PhaseTM 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-PhaseTM 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.

ARTICLE
ANALOG SIGNAL VS. DIGITAL SIGNALSARTICLEA signal is an electromagnetic or electrical current that carries data from one system or network to another. In electronics, a signal is often a time-varying voltage that is also an electromagnetic wave carrying information, though it can take on other forms, such as current. There are two main types of signals used in electronics: analog and digital signals. This article discusses the correspond...
