Dual Output 3 Phase & 2
Phase Controller with
Single SVID Interface for
Desktop and Notebook CPU
http://onsemi.com
Applications
The NCP6132A/NCP6132B dual output three plus two phase buck
solution is optimized for Intel IMVP7 and VR12 compatible CPUs.
The controller combines true differential voltage sensing, differential
inductor DCR current sensing, input voltage feedforward, and
adaptive voltage positioning to provide accurately regulated power for
both Desktop and Notebook applications. The control system is based
on DualEdge pulsewidth 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.
