MP2853GU Integrated Circuit Chip 5-Phase Dual-Loop Digital Controller With PMBus Interface
Product Overview Of MP2853
MP2853 is a dual-loop, digital, multi-phase controller that provides power for the core of the AMD SVI 2.0 platform. The MP2853 can be configured with up to 4-phase operation for Rail 1 and up to 2-phase operation for Rail 2.
MP2853 provides an on-chip EEPROM to store and restore device configurations. Device configurations and fault parameters can be programmed easily or monitored via the PMBus™/I2C interface. The MP2853 can monitor and report output current through the CS output from Intelli-Phase products.
