The HIP6302 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 microprocessors. 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. Multi-phase convertors, by distributing the power and load current results in smaller and lower cost transistors with fewer input and output capacitors.
