ISL68124
Digital Dual Output, 4-Phase Configurable, PWM Controller with PMBus
FN8796 Rev.2.00 June 16, 2017
The ISL68124 is a digital dual output, flexible multiphase (X+Y ≤ 4) PWM controller supporting the latest PMBus 1.3 specifications. Either output can be configured to support any desired phase assignments up to a maximum of four phases across the two outputs (X+Y). For example, 3+1, 2+2, 2+1, or even a single output operation as a 4+0 configuration are supported. The ISL68124 uses Intersil’s proprietary linear synthetic digital current modulation scheme to achieve the industry’s best combination of transient response and ease of tuning while addressing the challenges of modern multiphase designs.
