Mobile Microprocessor CORE Voltage Regulator Multi-Phase Buck PWM Controller

The ISL6223 multi-phase PWM control IC together with its companion gate drivers, the HIP6601, HIP6602 or HIP6603 and Intersil MOSFETs provides a precision voltage regulation system for advanced mobile microprocessors. A single-stage regulator that directly converts a battery voltage to a microprocessor core voltage can be designed when high voltage drivers are employed. Multiphase power conversion is a marked departure from earlier single phase converter configurations previously employed to satisfy the ever increasing current demands of modern microprocessors.
