Overview
The NCP6132, produced by onsemi, is a dual output three plus two phase buck solution optimized for Intel IMVP-7 and VR12 compatible CPUs. This controller is designed to provide accurately regulated power for both desktop and notebook applications. It combines true differential voltage sensing, differential inductor DCR current sensing, input voltage feed-forward, and adaptive voltage positioning to ensure high precision power delivery. The control system utilizes dual-edge pulse width modulation (PWM) combined with DCR current sensing, which offers the fastest initial response to dynamic load events and reduces system cost. Additionally, it can shed to single phase during light load operation and auto-frequency scale in light load while maintaining excellent transient performance.
