Shenzhen Mingjiada Electronics Co., Ltd. maintains a long-term supply of MP2890 components in stock. We also offer high-price buyback services nationwide for idle inventory and factory surplus of this model, providing comprehensive support—from component supply to inventory optimization—for servers, AI computing hardware, and data communication power solutions.
MP2890 Overview:
The MP2890 is a dual-channel digital multi-phase controller capable of powering core power supplies that utilize Pulse Width Modulation Voltage Identification (PWM-VID) control, while also being compatible with the AVSBus interface. The MP2890 can be used in conjunction with MPS’s Intelli-Phase™ products to implement a complete multi-phase voltage regulator (VR) solution with a minimum number of external components.
The MP2890 can be configured to operate with up to 20 phases on Rail 1 and up to 8 phases on Rail 2.
The device features on-chip non-volatile memory (NVM) for storing and restoring device configurations, and device configurations and fault parameters can be easily configured or monitored via the PMBus/I²C interface.
By monitoring the current-sampling output of the Intelli-Phase™ device, the MP2890 can monitor and report the output current (IOUT).
Based on a unique digital multiphase nonlinear control scheme, the device provides fast load transient response with minimal output capacitance. Since a single power-loop control method is used for both steady-state and load transients, power-loop compensation configuration is very simple.
The MP2890 is available in a QFN-64 (8 mm × 8 mm) package.
