ISL68134

DATASHEET ISL68134 Digital Dual Output, 4-Phase Configurable, PWM Controller with Adaptive Voltage Scaling Bus FN8817 Rev.1.00 Jun 19, 2017 The ISL68134 is a digital dual output, flexible multiphase (X+Y ≤ 4) PWM controller with Adaptive Voltage Scaling (AVSBus) interface. 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 flexible phase arrangement, combined with PMBus and AVSBus interfaces, allows the device to support any demanding power supply requirement. The ISL68134 with AVSBus complements PMBus by providing a common interface that accelerates point-to-point communication between the controller and the load to statically and dynamically control processor voltage, thus delivering a balanced and power efficient solution. AVSBus can be used exclusively after the device is configured using PMBu...
