DESCRIPTION The MP2884A is a digital, multi-phase, pulsewidth modulation (PWM) controller with digital PWM-VID interface compatible with NVIDIA’s Open VReg specification. The MP2884A can work with MPS’s Intelli-Phase products to complete the multi-phase voltage regulator (VR) solution with minimal external components. The MP2884A can be configured with up to 4-phase operation. The MP2884A 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 MP2884A can monitor and report the output current through the CS output from the Intelli-Phase products.
