Microprocessor CORE Voltage Regulator Multi-Phase Buck PWM Controller FN4840 Rev 0.00 March 2000 The HIP6304 multi-phase PWM control IC together with its panion 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. These reductions accrue from the higher effective conversion frequency with higher frequency ripple current due to the phase interleaving process of this topology. For example, a two phase convertor operating at 350k Hz will have a ripple frequency of 700k Hz. Moreover, greater convertor bandwidth of this design results...
