ISL68236数据手册Renesas中文资料规格书

描述 Description

The ISL68236 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 allows the device to support any demanding power supply requirement.

Additionally, the ISL68236 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 ISL68236 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 Renesas 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.
