L6758A

High performance (4+1) dual controller for the VR12

Datasheet

production data

Applications

• High-current VRM / VRD for desktops / servers

/ workstations / new generation CPUs

Description

L6758A is a dual controller designed to

power Intel^®VR12 processors: all required

parameters are programmable through dedicated

pinstrapping.

VFQFPN48 - 6x6 mm

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.

Features

• VR12 compliant with 25 MHz SVID bus rev 1.5

– serialVID with programmable IMAX, TMAX,

VBOOT, ADDRESS

• Second generation LTB Technology^™

• Dual controller:

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

– two-to-four phase for core

– 1 phase for graphics (GFX) or system

agent (VSA)

• Single NTC design for TM, LL and IMON

independent protection against load overcurrent,

under/overvoltage and feedback disconnections.
