Description

L6758A is a dual controller designed to

power Intel

®

VR12 processors: all required

parameters are programmable through dedicated

pinstrapping.

The device features two-to-four phase

programmable operation for multi-phase sections

and a single-phase with independent control

loops. Both sections feature second generation

LTB Technology to provide fast load transient

response, minimizing and optimizing the output

filter composition.

The L6758A supports power state transitions

featuring VFDE, programmable DPM and GDC,

maintaining the best efficiency over all loading

conditions without compromising transient

responses. The device assures fast and

independent protection against load overcurrent,

under/overvoltage and feedback disconnections.

The device is available in VFQFPN48 package.
