Description

The L6751B is a universal digitally controlled dual

PWM DC-DC designed to power Intel’s VR12 and

AMD SVI processors and memories: all required

parameters are programmable through dedicated

pinstrapping and PMBus interface.

The device features up to 6-phase programmable

operation for the multi-phase section and a single-

phase with independent control loops. When

configured for memory supply, single-phase

(VTT) reference is always tracking multi-phases

(VDDQ) scaled by a factor of 2. The L6751B

supports power state transitions featuring VFDE,

programmable DPM and GDC maintaining the

best efficiency over all loading conditions without

compromising transient response. The device

assures fast and independent protection against

load overcurrent, under/overvoltage and feedback

disconnections.

The device is available in VFQFPN68 8x8 mm

package.
