概要
説明
The ISL68225 is a digital dual output multiphase (X+Y ≤ 9) PWM controller supporting PMBus v1.3/AVSBus interfaces. The controller can be configured to support phase assignments up to a maximum of nine phases across the two outputs (X and Y). For example, 8+1, 7+2, 6+3, 5+4, or a single output operation as a 9+0 configuration is supported. Increased power density and PMBus v1.3 interface support allow the devices to support any demanding power supply requirement.
The ISL68225 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.
