ISL69147 FN8706 Rev.6.00 Digital Dual Output 7-Phase AMD PWM Controller Feb 15, 2019 The ISL69147 is a digital dual output multiphase (X + Y = 7) Features PWM controller that is compliant with AMD SVI2 Advanced linear digital modulation scheme specifications. The digital multiphase controller can be configured to support any phase assignments across the two - Zero latency synthetic current control for excellent high outputs (X and Y). The ISL69147 supports the PMBus V1.3 and frequency current balance SVI2 interfaces, so the device is ideal for controlling the - Auto phase add/drop for excellent load vs efficiency microprocessor core, memory, and system rails for AMD SVI2 profile based platforms. When the ISL69147 is configured to use the - Excellent DVID performance SVI2 interface, Rail 1 can support a maximum of six phases - Dual edge modulation for faster transient response and Rail 2 must have one phase assigned. Up to 1MHz operation for high density designs The ISL69147 uses a proprietary digital linear synthetic Diode braking for overshoot reduction current modulation scheme to achieve the industrys best combination of transient response and ease of tuning while Diode emulation for enhanced light-load efficiency addressing the challenges of powering the latest generation of Differential remote voltage sensing supports 0.5% AMD microprocessors. You can use the intuitive Renesas closed-loop system accuracy over load, line, and PowerNavigator software to configure the device. Diode temperature emulation and automatic phase add/drop features allow you to extract maximum efficiency from the converter regardless Highly accurate current sensing for excellent load line of load conditions. regulation and accurate OCP - Supports ISL99227 60A smart power stages The ISL69147 supports a comprehensive fault management - Supports DCR sense with integrated temperature system to enable the design of highly reliable systems. From compensation an overcurrent protection scheme including peak and average detection, to configurable power-good and catastrophic fault Supports phase doubler (ISL6617A) for up to 14-phase protection flags, almost any need is accommodated. operation With minimal external components, the ability to store eight Comprehensive fault management enables high reliability configurations, robust fault management, and highly accurate systems regulation capability, implementing a high performance - Pulse-by-pulse phase current limiting multiphase regulator has never been easier. - Total output current protection - Output and input OV/UV protection Applications - Open voltage sense detect Core and graphics for AMD SVI2 based processors - Black box recording capability for faults - High performance servers core rail - Configurable catastrophic failure flag output (CFP) - High performance graphic rail Intuitive configuration using PowerNavigator - High-end desktop with overclocking option Networking, data center, storage, and general purpose SMBus/PMBus V1.3 compatible - Up to 2MHz bus interface Related Literature - NVM to store up to eight configurations For a full list of related documents, visit our website: Pb-free (RoHS compliant) ISL69147 product page FN8706 Rev.6.00 Page 1 of 3 Feb 15, 2019ISL69147 Typical Application: VR with ISL99227 Targeting SVI2 Processor Rails RGND1 VSEN1 1k EN1 VCCS PG1 4.7F 100 nSMOD1 TEMP1 ISL99227 3.3V VCC PVCC 5V 4.7F VCC PWM0 PWM LGCTRL CS0 IMON VIN 12V 2x22F CSRTN0 REFIN BOOT 0.1F 47pF TMON PHASE FAULT GND SW 12V 470pF ISL99227 40.2k VDD1 PVCC 5V 0.1F VINSEN C VCC OUT PWM1 PWM LGCTRL 10k CS1 IMON VIN 12V 2x22F CSRTN1 REFIN BOOT 0.1F 0.01F 47pF TMON PHASE FAULT GND SW ISL69147 ISL99227 1.8V VDDIO PVCC 5V 4.7F 0.1F VCC PWM2 PWM LGCTRL CS2 IMON VIN 12V PWROK 2x22F CSRTN2 REFIN BOOT 0.1F 47pF TMON PHASE SVC FAULT GND SW SVD ISL99227 SVT PVCC 5V 0.1F VCC PWM3 PWM LGCTRL CS3 IMON VIN 12V 2x22F CSRTN3 REFIN BOOT 0.1F 47pF nVRHOT TMON PHASE FAULT GND SW ISL99227 CFP PVCC 5V 0.1F VCC PWM4 PWM LGCTRL CS4 IMON VIN 12V 2x22F CSRTN4 REFIN BOOT 0.1F 47pF TMON PHASE FAULT GND SW PMSCL ISL99227 PMSDA 0.1F PVCC 5V VCC nPMALERT PWM5 PWM LGCTRL ADDRESS CS5 IMON VIN 12V 2x22F CSRTN5 REFIN BOOT 0.1F 47pF TMON PHASE FAULT GND SW ISL99227 CONFIG VDD2 0.1F PVCC 5V C VCC OUT PWM6 PWM LGCTRL CS6 IMON VIN 12V 2x22F REFIN CSRTN6 BOOT 0.1F 47pF TMON TEMP2 PHASE FAULT GND SW nSMOD2 0.1F PG2 470pF 1k EN2 RGND2 VSEN2 FIGURE 1.
