About This Product

■Summary

The MP2853 is a dual-loop, digital, multiphase controller that powers the core of the AMD SVI 2.0 platform. The MP2853 works with MPS' Intelli-Phase products to complete a multiphase voltage regulator (VR) solution with minimal external components. The MP2853 is configurable with up to 4-phase operation for rail 1 and up to 2-phase operation for rail 2. MP2853 provides on-chip EEPROM for saving and restoring device settings. Device configuration and fault parameters can be easily programmed and monitored via the PMBusTM/I2C interface. The MP2853 can monitor and report output current through the CS output from Intelli-Phase products. The MP2853 is based on a proprietary digital multiphase, nonlinear control that provides fast transient response to load transients with minimal output capacitance. Setting up power loop compensation is very simple since there is only one power loop control method for both steady state and load transients. The MP2853 is available in a QFN-40 (5mm x 5mm) package.

■Features and benefits

・Multi-phase, dual output, digital controller ・AMD SVI 2.0 compliant ・Supports 3-bit PVID mode ・PMBusTM / I2C compliant (1MHz bus speed) -Pin programmable for PMBusTM address -Built-in EEPROM to save custom settings ・Switching frequency range from 200kHz to 3MHz ・Digital load line regulation ・Overclocking mode by adding an offset to the output voltage ・Automatic loop compensation ・Fewer external components than conventional analog controllers ・Best transient performance with nonlinear digital control ・Flexible phase assignment of dual rails ・Automatic phase shedding to improve overall efficiency - Phase-to-phase active current balance with programmable offset to thermal balance ・Monitoring of input/output voltage, current, and power ・Regulator temperature monitoring
