Remark

ISL95857CHRTZ-T General Description

The ISL95857C provides a complete power solution for Intel microprocessors supporting core, graphics, and system agent rails and is compliant with Intel IMVP8. The controller provides control and protection for three Voltage Regulator (VR) outputs. The VR A and VR C outputs support 1-phase operation only, while VR B is configurable for 2- or 1-phase operation. The address options programmable for these three outputs allow for maximum flexibility in support of the IMVP8 CPU. All three VRs 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 (DE) mode with load-dependent low switching frequency. The controller provides PWM outputs, which support Intel DrMOS power stages (or similar) and discrete power stages using the Intersil ISL95808 high voltage synchronous rectified buck MOSFET driver. The controller complies with IMVP8 PS4 power requirements and supports compatible power stages and drivers. The ISL95857C supports the system input power monitor (PSYS) option. 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. All three outputs feature remote voltage sense, programmable I_MAX, adjustable switching frequency, OC protection, and a single VR_READY power-good indicator.
