NCP6121

Preliminary Datasheet

Dual Output 3 Phase +1/0 Phase

Controller with single SVID Interface

for Desktop CPU Applications

The NCP6121 dual output three plus one phase buck

solution is optimized for Intel 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 Desktop 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.

Dual high performance operational error amplifiers are

provided to simplify compensation of the system.

Patented Dynamic Reference Injection further simplifies

loop

compromise between closed-loop transient response

and Dynamic VID performance. Patented Total Current

Summing provides highly accurate current monitoring for

droop and digital current monitoring.
