Description
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.

ISL68227 PG Leakage Current
Hi, We have been bringing up a new board which uses ISL68227 12-phase PWM controller. We found that the Power-Good voltage on pin PG0 was not as expected. It appeared that the PG leakage current was not 5uA as stated on ISL68227 datasheet Rev 1.00, but ~20uA ...
