ISL68134
Digital Dual Output, 4-Phase Configurable, PWM Controller with Adaptive Voltage
Scaling Bus
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 PMBus. The
ISL68134 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. FN8817
