ISL68137
Digital Dual Output, 7-Phase Configurable PWM Controller with Adaptive Voltage
Scaling Bus (AVSBus)
The ISL68137 is a digital dual output, flexible multiphase
(X+Y ≤ 7) PWM controller with Adaptive Voltage Scaling Bus
(AVSBus) interface. The ISL68137 can be configured to
support any desired phase assignments up to a maximum of
seven phases across the two outputs (X+Y). For example, 6+1,
5+2, 4+2, 3+3, 3+2, or even a single output as a 7+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 ISL68137 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 the processor voltage, thus
delivering a balanced and power-efficient solution. AVSBus can
be used exclusively after the device is configured using PMBus.
The ISL68137 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. …
