概要
説明
The ISL68233 is a digital dual output multiphase (X+Y ≤ 5) PWM controller supporting PMBus v1.3/AVSBus interfaces. The controller can be configured to support any phase assignments up to a maximum of five phases across the two outputs (X and Y). For example, 4+1, 3+2, 3+1, 1+1, or a single output operation as a 5+0 configuration is supported. Increased power density and PMBus v1.3 interface support allow the ISL68233 to support any demanding power supply requirement.
The ISL68233 with AVSBus complements PMBus by providing a common high-speed interface to accelerate point-to-point communication between the controller and load to statically and dynamically control the processor voltage and deliver a balanced, power-efficient design.
The ISL68233 uses the proprietary Renesas digital synthetic current modulation scheme to achieve the industry-best combination of transient response, ease of tuning, and efficiency across the full load range. Diode emulation and automatic phase add/drop features allow you to extract maximum efficiency from the converter regardless of load conditions. You can use the intuitive PowerNavigator™ software to configure and monitor the device.
With minimal external components, easy configuration, robust fault management, and highly accurate regulation capability, implementing a high-performance, multiphase regulator has never been easier.
