ISL95820 Green Hybrid Digital Four Phase PWM Controller

Green Hybrid Digital Four Phase PWM Controller for Intel VR12.5™ CPUs ISL95820 The ISL95820 Pulse Width Modulation (PWM) controller IC provides a complete low-cost solution for Intel VR12.5™ compliant microprocessor core power supplies. It provides the control and protection for a Voltage Regulator (VR). The VR incorporates 3 integrated drivers and can operate in 4-, 3-, 2or 1-phase configurations. The VR uses a serial control bus to communicate with the CPU and achieve lower cost and smaller bo.

ISL95820 Features

* It supports either DCR current sensing with a single NTC thermistor for DCR temperature compensation, or more precise resistor current sensing if desired. The output comes with remote voltage sense, programmable VBOOT voltage, IMAX, voltage transition slew rate and switching frequency, adjustable o
