1 / 31 page © Semiconductor Components Industries, LLC, 2012 March, 2012 − Rev. P1 1 Publication Order Number: NCP6132A/D NCP6132A, NCP6132B Product Preview Dual Output 3 Phase & 2 Phase Controller with Single SVID Interface for Desktop and Notebook CPU Applications The NCP6132A/NCP6132B dual output three plus two phase buck solution is optimized for Intel IMVP−7 and VR12 compatible CPUs. The controller combines true differential voltage sensing, differential inductor DCR current sensing, input voltage feed−forward, and adaptive voltage positioning to provide accurately regulated power for both Desktop and Notebook applications. The control system is based on Dual−Edge pulse−width modulation (PWM) combined with DCR current sensing providing the fastest initial response to dynamic load events and reduced system cost. It also sheds to single phase during light load operation and can auto frequency scale in light load while maintaining excellent transient performance. There are three internal MOSFET drivers inside the chip. One of these three integrated driver can be configured either to drive core phase or aux phase. NCP6132A and NCP6132B have almost same structure except that NCP6132A has two integrated drivers for the core rail and one integrated driver for auxiliary rail, while the NCP6132B has all three integrated drivers for the core rail.
