ISL68223数据手册集成电路（IC）的PMIC-稳压器-DCDC开关式控制器规格书PDF

描述 Description

The ISL68223 is a digital dual output multiphase (X+Y ≤ 4) PWM controller with PMBus V1.3. The controller can be configured to support any desired phase assignments up to a maximum of four phases across the two outputs (X and Y). For example, 3+1, 2+2, 2+1, 1+1, or even single output operation as a 4+0 configuration are supported. Increased power density, combined with support for PMBus V1.3 interface, allows the device to support any demanding power supply requirement.

The ISL68223 uses the Renesas proprietary 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.
