L6718

Digitally controlled dual PWM with embedded drivers for VR12

processors

Datasheet - production data

Applications

• High-current VRM / VRD for desktop / server /

new generation workstation CPUs

• DDR3 DDR4 memory supply for VR12

VFQFPN56 -7x7 mm

Description

The L6718 is a very compact, digitally controlled

and cost effective dual controller designed to

power Intel^®VR12 processors. Dedicated

pinstrapping is used to program the main

parameters.

Features

• VR12 compliant with 25 MHz SVID bus rev. 1.5

• Second generation LTB Technology^™

• Very compact dual controller:

The device features from 2 to 4-phase

programmable operation for the core section

providing 2 embedded drivers. A single-phase

with embedded driver and with independent

control loop is used for GFX.

– Up to 4 phases for core section with 2

internal drivers

– 1 phase for GFX section with internal driver

• Input voltage up to 12 V

• SMBus interface for power management

• SWAP, Jmode, multi-rail only support

• Programmable offset voltage

The L6718 supports power state transitions

featuring VFDE and a programmable DPM,

maintaining the best efficiency over all loading

conditions without compromising transient

response.

• Single NTC design for TM, LL and IMON

thermal compensation (for each section)

Second generation LTB Technology^™allows a

minimal cost output filter providing fast load

transient response. The controller assures fast

and independent protection against load

overcurrent, under/overvoltage and feedback

disconnections.

• VFDE for efficiency optimization

• DPM - dynamic phase management

• Dual differential remote sense

• 0.5% output voltage accuracy

• Full-differential current sense across DCR

• AVP - adaptive voltage positioning

• Programmable switching frequency

• Dual current monitor

The device is available in VFQFPN56, 7x7 mm

compact package with exposed pad.
