4/5/6 Phase Controller

The NCP5382 is a two, three, four, five or six phase buck controller which combines differential voltage and current sensing and adaptive voltage positioning to power Intel's most demanding Pentium® IV Processors and low voltage, high current power supplies. Dual edge pulse width modulation, combined with inductor current sensing rduces system cost by providing the fastest initial response to transient loads thereby requiring less bulk and ceramic output capacitors to satisfy transient load line requirements. A high performance operational error amplifier is provided, which allows easy compensation of the system. the proprietary mehtod of Dynamic Reference Injection makes the error amplifer compensation virtually independent of hte system response to VID changes, eliminating the need for tradeoffs between load transients and Dynamic VID performance
