ISL68127 PWM Controller with PMBus The ISL68127IRAZ is a digital dual output, flexible multiphase (X+Y ≤ 7) PWM controller supporting the latest PMBus V1.3 specifications. The ISL68127can be configured to support any desired phase assignments up to a maximum of seven phases across the two outputs (X+Y). 

You can configure the device and monitor telemetry using the intuitive Renesas PowerNavigator GUI. The ISL68127 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 automatic phase add / drop feature allows maximum efficiency across all load ranges. Thresholds for automatic phase add/drop are user-programmable using PowerNavigator.

The ISL68127 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.
