Description
The ISL68220 is a digital dual output multiphase (X+Y ≤ 2) PWM controller with PMBus V1.3 compatibility. The controller can be configured to support any required phase assignments up to a maximum of two phases across the two outputs (X and Y). For example, 1+1, 1+0, or even single output operation as a 2+0 configuration are supported. When combined with the Renesas family of Smart Power Stages and DrMOS devices, designs of exceptional density and performance can be created.
The ISL68220 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™ 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.
