About This Product

■Summary

The MP2965 is a dual-loop, digital multiphase controller that powers the Intel VR13.HC platform and AVSBus-controlled CPU cores. The MP2965 works with MPS' Intelli-Phase products to complete a multiphase voltage regulator (VR) solution with a minimum of external components. The MP2965 is configurable for up to 7-phase operation on rail 1 and up to 3-phase operation on rail 2. MP2965 provides on-chip EEPROM for saving and restoring device settings. Device configuration and fault parameters can be easily programmed or monitored via the PMBus/I2C interface. The MP2965 can monitor and report output current through the CS output from Intelli-Phase products. The MP2965 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.

■Features and benefits

・Multi-phase, dual output, digital controller ・Intel VR13.HC/IMVP9 compliant ・PMBus/I2C and AVSBUS compliant ・Switching frequency up to 3MHz - Programmable pin for PMBus or start-up voltage -Built-in EEPROM to save custom settings ・Automatic loop compensation ・Fewer external components than conventional analog controllers ・Reduction of overshoot by non-linear 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 ・Digital load line regulation ・Intelli-Phase MOSFET failure type detection and automatic recording to EEPROM ・Supports 3-bit PVID mode ・Supports overclocking mode ・Line floating detection ・Monitoring of input/output voltage, current, and power ・Regulator temperature monitoring UVLO, OVP, UVP, OCP, and OTP with no-action, latch, retry, or hiccup options
