Digital Multi-Phase PWM Controller for Core-Voltage Regulation
Processors that operate above a GHz require fast, intelligent power systems. The Intersil ISL6590 controller offers intelligent digital, multi-phase control that provides high bandwidth, optimal control frequency response, noise immunity and active transient response control algorithms. The design is fully scalable for controlling up to six phases, each featuring the Intersil ISL6580 intelligent power stage. The user can configure and monitor the power system via the Asynchronous Serial Interface (ASI). The ISL6590 controller flexibility can be extended with the addition of an external...
