The ISL68134 is a digital dual output, flexible multiphase (X+Y ≤ 4) PWM controller with Adaptive Voltage Scaling interface (AVSBus). Either output can be configured to support any desired phase assignments up to a maximum of four phases across the two outputs (X+Y). For example, 3+1, 2+2, 2+1, or even a single output operation as a 4+0 configuration are supported. The flexible phase arrangement, combined with PMBus and AVSBus interfaces, allows the device to support any demanding power supply requirement. The ISL68134 with AVSBus complements PMBus by providing a common interface that accelerates point-to-point communication between the controller and the load to statically and dynamically control processor voltage, thus delivering a balanced and power efficient solution. AVSBus can be used exclusively after the device is configured using PMBus. The ISL68134 uses Intersil’s proprietary linear synthetic digital current modulation scheme to achieve the industry’s best combination of transient response and ease of tuning while addressing the challenges of modern multiphase designs. Device configuration and telemetry monitoring is accomplished using Intersil's intuitive PowerNavigator™ GUI. The ISL68134 device supports on-chip nonvolatile memory to store various configuration settings that are user selectable through pin-strap, giving system designers increased power density to configure and deploy multiple configurations. The device supports an automatic phase add/drop feature to allow maximum efficiency across all load ranges. Thresholds for automatic phase add/drop are user programmable using the powerful PowerNavigator GUI. The ISL68134 supports a comprehensive fault management system to enable the design of highly reliable systems. From a multitiered overcurrent protection scheme, to the configurable power-good and output overvoltage/undervoltage fault thresholds and temperature monitoring, almost any need is accommodated. With minimal external components, easy configuration, robust fault management and highly accurate regulation capability, implementing a high performance multiphase regulator has never been easier.
