ISL68144
Digital Dual Output, 4-Phase Configurable, PWM Controller with PMBus for Cavium
FN8888 Rev. 3.00 Feb 8, 2018
The ISL68144 is a digital dual output, flexible multiphase (X+Y ≤ 4) PWM controller developed to support the latest Cavium CN99xx server class processors. The ISL68144 supports the PMBus 1.3 specification and is designed to meet the latest Intel server-class transient performance 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), such as 3+1, 2+2, 2+1, or even a single output operation as a 4+0 configuration.
