Description
The ISL95866C is compliant with Intel IMVP8™, and provides a complete power solution for desktop microprocessors supporting core (IA), graphics (GT), or unsliced graphics (GTUS or GTX). The controller provides control and protection for two Voltage Regulators (VR). The first VR can be configured for 4-, 3-, 2-, or 1-phase operation. The second VR is configurable for 3-, 2-, or 1-phase operation. The VRs feature a programmable SVID address to allow maximum flexibility in supporting desktop processor SKUs. Both controller outputs share a common serial control bus to communicate with the CPU and achieve lower cost and smaller board area compared with a two-chip approach. Based on Intersil’s Robust Ripple Regulator R3™ technology, the R3 modulator has many advantages compared to traditional modulators. These include faster transient settling time, variable switching frequency in response to load transients, and improved light-load efficiency due to Diode Emulation Mode with load-dependent low switching frequency. The ISL95866C has several other key features. The controller features three integrated +12V gate drivers with two on the VR A output. The controller supports either DCR current sensing with a single NTC thermistor for DCR temperature compensation or more precision through resistor current sensing if desired. Both outputs feature remote voltage sense, programmable IMAX, adjustable switching frequency, OC protection, and a single VR_READY power-good indicator. The ISL95866C features an SMBus interface, which supports enabling or disabling droop, output voltage offset adjustment, and disabling of OVP and OCP protections.
