ISL69122
Digital Dual Output, 4-Phase Configurable, VR13 PWM Controller with SVID and 2-Bit AVID Interfaces
FN8970 Rev. 0.00 Feb 1, 2018
The ISL69122 is a digital dual output, flexible multiphase (X+Y ≤ 4) PWM controller that is compliant with Intel VR13 specifications. The digital multiphase 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, or even single output operation as a 4+0 configuration are supported. With a flexible X+Y ≤ 4 phase assignment along with PMBus and AVID interfaces, the ISL69122 is ideal for controlling the microprocessor core, memory, and system rails of Intel VR13 platforms.
The ISL69122 uses the proprietary Renesas digital linear synthetic current modulation scheme to achieve the industry’s best combination of transient response and ease of tuning while ad.
