Digital Multiphase Controllers for General Applications
The ISL68137 and ISL68134 controllers utilize the AVSBus to power and communicate with ARM-based processors in network routers, switches, servers, storage, and wireless telecom equipment. Two general-purpose controllers (ISL68127 and ISL68124) power network processors, FPGAs, SoCs and graphics accelerators.

ISL68137 7-Phase Digital Multiphase PWM Controller with AVSBus
The ISL68137 can be configured to support any desired phase assignments up to a maximum of 7 phases across the 2 outputs (X+Y).
PowerNavigator™ Software v5.3 for Digital Power Products
PowerNavigator™ v5.3 includes PowerMap, Rail Inspector and RailScope features to simplify design of densely populated power systems.
Intersil's digital multiphase controllers and a companion smart power stage provide up to seven phases assignable in any combination across two outputs. Our PowerNavigator™ software tool makes it easy to set up and control all parameters, optimize efficiency and adjust the loop tuning. PowerNavigator eliminates board rework as designs are completed with on the fly changes for stability tuning and optimization.
The ISL681xx and ISL691xx controllers integrate a high performance digital engine featuring a patented synthetic current control architecture that tracks each phase current with zero latency. This allows the device to respond to any load transient with precise current and voltage positioning, and 30% less capacitance than competitive devices. Synthetic current control also makes it possible to develop high reliability systems using all ceramic capacitors.
AVSBus joins the PMBus™ v1.3 specification and features a 50MHz high-speed bus that connects directly to the processor to communicate telemetry data and deliver efficiency savings through adaptive voltage positioning. Intersil's digital multiphase DC/DC controllers and ISL99227 60A smart power stage support demanding CPU core voltages, memory, and auxiliary power rails, enabling power designers to customize their solution to meet any rail requirements.
