Overview
Datasheet ISL68227 Digital Single Output,12-Phase PWM Controller The ISL68227 is a digital multiphase (X ≤ 12) PWM controller with PMBus V1.
3 compatibility.
The digital multiphase controller can be configured to support any phase assignment up to a maximum of 12 phases.
Increased power density, combined with support for PMBus V1.
3 allows the ISL68227 to support any demanding power supply requirements.
The ISL68227 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.
