L6759D

3+1 dual controller for VR12 with PMBus

Datasheet − production data

Features

■ VR12 compliant with 25 MHz SVID bus Rev1.5

– SerialVID with programmable IMAX,

TMAX, VBOOT, ADDRESS

■ Second generation LTB Technology™

■ Flexible driver/DrMOS support

■ JMode support

VFQFPN48 - 6x6mm

Description

■ Fully configurable through PMBus

The L6759D is a dual controller designed to

power Intel’s VR12 processor memories: all

required parameters are programmable through

dedicated pin-strapping and PMBus interface.

■ Dual controller:

– 3-phase for VDDQ

– 1-phase for VTT

■ Single NTC design for TM, LL and Imon

The device features 3-phase programmable

operation for the multi-phase section and a single-

phase with independent control loops. Single-

phase (VTT) reference is always tracking multi-

phases (VDDQ) scaled by a factor of 2.

thermal compensation

■ VFDE and GDC - gate drive control for

efficiency optimization

■ DPM - dynamic phase management

■ Dual remote sense

The L6759D supports power state transitions

featuring VFDE, programmable DPM and GDC

maintaining the best efficiency over all loading

conditions without compromising transient

response.

■ 0.5% output voltage accuracy

■ Full-differential current sense across DCR

■ AVP - adaptive voltage positioning

■ Dual independent adjustable oscillator

■ Dual current monitor

The device assures fast and independent

protection against load overcurrent,

under/overvoltage and feedback disconnections.

■ Pre-biased output management

■ Average and per-phase OC protection

■ OV, UV and FB disconnection protection

■ Dual VR_RDY

The device is available in a VFQFPN48 6x6 mm

package.
