About This Product

■Summary

The MP2888A is a digital, multiphase, pulse-width modulation (PWM) controller with a digital PWM-VID interface compatible with NVIDIA's Open VReg specification. The P2888A works with MPS' Intelli-Phase products to complete a multiphase voltage regulator (VR) solution with minimal external components. MP2888A can be configured with up to 10 phase operation. MP2888A provides on-chip EEPROM to save and restore device settings. Device configuration and fault parameters can be easily programmed or monitored via the PMBus/I2C interface. The MP2888A can monitor and report output current through the CS output from Intelli-Phase products. The MP2888A 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 MP2888A is available in a QFN-40 (5mm x 5mm) package.

■Features and benefits
