The ISL68127 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). For example, 6+1, 5+2, 4+2, 3+3, 3+2, or even a single output operation as a 7+0 configuration are supported. The ISL68127 uses the Renesas 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. 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. With minimal external components, easy configuration, robust fault management, and highly accurate regulation capability, implementing a high-performance, multiphase regulator has never been easier.

特長

  • Zero latency synthetic current control for excellent HF current balance
  • Dual edge modulation for fastest transient response
