About This Product

■Summary

The MP2880 is a single-loop digital multiface controller that powers memory and systems-on-chip (SoC). The MP2880 works with MPS' Intelli-PhaseTM products to provide a complete multiphase voltage regulator (VR) solution with minimal external components. The MP2880 can be configured with up to 20 phase operation. The MP2880 provides on-chip non-volatile memory (NVM) for saving and restoring device settings. Device configuration and fault parameters can be easily configured or monitored via PMBus/I2C interface. The device can monitor and report output current (IOUT) through an Intelli-PhaseTM current sense (CS) output. The MP2880 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 easy because there is only one power loop control method for both steady state and load transients. The MP2880 is available in a TQFN-56 (7mm x 7mm) package.

■Features and benefits

・Multi-phase, single output, digital controller ・PMBus / I2C compliant (1MHz bus speed) ・AVSBus compliant ・Couple inductor mode ・N+2 phase redundancy function ・Built-in non-volatile memory (NVM) for saving custom settings ・Multi-configuration with pin straps (up to 16) ・Switching frequency (fSW) range from 200kHz to 3MHz ・Automatic loop compensation ・Fewer external components than conventional analog controllers ・Best transient performance with nonlinear digital control ・Single rail flexible phase assignment - Automatic phase shedding (APS) to improve overall efficiency Active current balance between phases with configurable offset for thermal balance ・Input voltage (VIN) and output voltage (VOUT), current, and power monitoring ・Regulator temperature monitoring
