Resources for ISL95712
Description
The ISL95712 is fully compliant with AMD Fusion™ SVI 2. 0 and provides a complete solution for microprocessor and graphics processor core power. The ISL95712 controller supports two Voltage Regulators (VRs) for Core and Northbridge outputs. The Core VR can be configured for 4-, 3-, 2-, or 1-phase operation while the Northbridge VR supports 3-, 2- or 1-phase configurations for maximum flexibility. The two VRs share a serial control bus to communicate with the AMD CPU and achieve lower cost and smaller board area compared with two-chip solutions. The PWM modulator is based on Intersil’s Robust Ripple Regulator R3™ Technology. Compared to traditional modulators, the R3™ modulator can automatically change switching frequency for faster transient settling time during load transients and improved light load efficiency. The ISL95712 has several other key features. Both outputs support DCR current sensing with a single NTC thermistor for DCR temperature compensation or accurate resistor current sensing. They also utilize remote voltage sense, adjustable switching frequency, OC protection and power-good indicators.
