NCP5389 2/3 Phase Buck Controller for VR11 Pentium IV Processor Applications The NCP5389 is a two− or three−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 (PWM) combined with inductor current sensing reduces 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.
