The ISL68147 is a digital dual output, flexible multiphase (X+Y ≤ 7) PWM controller developed to support the latest Cavium CN99xx server class processors. The ISL68147 supports the PMbus1. 3 specification and meets the latest Intel server-class transient performance specifications. Either output can be configured to support any desired phase assignments up to a maximum of seven phases across the two outputs (X+Y). For example, 6+1, 5+2, 4+2, 3+3, 3+2, or even a single output operation as a 7+0 configuration. With full digital control, this new generation of controllers ushers in design flexibility by supporting any microprocessor, FPGA, or Digital ASIC rail requirements that includes adjustable load setting. The ISL68147 uses the Intersil 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 the Intersil PowerNavigator™ GUI. The ISL68147 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 PowerNavigator. The ISL68147 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.
