ISL95820 - Green Hybrid Digital Four Phase PWM Controller

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 overcurrent protection and Power-Good signal. Features.
  • Serial data bus.
  • SMBus/PMBus/I2C interface with SVID conflict free.
  • Configurable 4-, 3-, 2- or 1-phase for the output.

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 board area. The VR utilizes Intersil’s Robust Ripple Regulator R3 Technology™.
