Description

The L6751 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 multi-phase sections and a single-phase with

independent control loops. When configured for

memory supply, single-phase (VTT) reference is

always tracking multi-phase (VDDQ) scaled by a

factor of 2. The L6751 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 WLPGA72 6x6 mm

package.
