Description

The L6751C device 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 pin-strapping

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 L6751C 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 WPLGA72 6 x 6 mm

package.
