About This Product

■Summary

The MP2891 is a dual-rail, digital, multiphase controller that powers NVIDIA PWM VID core supplies. The MP2891 works with MPS' Intelli-PhaseTM products to complete a multiphase voltage regulator (VR) solution with a minimum of external components. The MP2891 is configurable for up to 16 phases on rail 1 and up to 8 phases on rail 2. MP2891 can save and restore device settings. You can configure and monitor device settings and fault parameters. The MP2891 monitors and reports output current (IOUT) through the current sense output from the Intelli-PhaseTM product. The MP2891 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 MP2891 is available in a QFN-56 (7mm x 7mm) package.

■Features and benefits

・Up to 16 phases, 2 outputs, digital controller ・PWM-VID compatible with NVIDIA's Open VReg specification (OVR4i+) ・Save settings ・Switching frequency (fSW) from 200kHz to 3MHz ・Automatic loop compensation ・Couple inductor mode ・Supports multi-configuration of 6 different applications -Flexible Pulse Width Modulation (PWM) assignment for 2 rails 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 ・VIN undervoltage lockout function (UVLO), output overvoltage protection (OVP), undervoltage protection (UVP), overcurrent protection (OCP), overtemperature protection (OTP), no-action, latch-off, hiccup options included ・Intelli-PhaseTM fault diagnosis ・Digital load line regulation ・Overclocking mode by adding offset to VOUT ・Provided in QFN-56 (7mm x 7mm) package
