Rev 1.00
January 14, 2014 4-Phase PWM Controller for VR12.5 and VR12.6 CPUs Features The ISL95816A Pulse Width Modulation (PWM) controller IC
provides a complete solution for VR12.5в„ў and VR12.6в„ў
compliant microprocessor core power supplies. It provides the
control and protection for a Voltage Regulator (VR). The VR can
operate in 4-, 3-, 2-or 1-phase configurations. The VR uses a
serial control bus to communicate with the CPU and achieve
lower cost and smaller board area. Serial data bus Configurable 4-, 3-, 2-or 1-phase R3в„ў Modulator
-Excellent transient response
-High light load efficiency The VR utilizes Intersil’s Robust Ripple Regulator
R3 Technologyв„ў. The R3в„ў modulator has numerous
advantages compared to traditional modulators, including
faster transient response, variable switching frequency during
load transients, and improved light load efficiency due to its
ability to automatically change switching frequency. 0.5% System accuracy over-temperature Supports multiple current sensing methods
-Lossless inductor DCR current sensing
-Precision resistor current sensing Differential remote voltage sensing The ISL95816A has several other key features. It supports
either DCR current sensing with a single NTC thermistor for
DCR temperature compensation, or more precise resistor
current sensing if desired; remote voltage sense;
programmable VBOOT voltage, IMAX, voltage transition slew …
