L6740L

Hybrid controller (4+1) for AMD SVID and PVID processors

Features

■ Hybrid controller: compatible with PVI and SVI

CPUs

■ Dual controller: 2 to 4 scalable phases for CPU

CORE, 1 Phase for NB

■ Dual-Edge asynchronous architecture with

HTQFP48

LTB technology

■ PSI management to increase efficiency in

Description

Light-Load conditions

L6740L is a hybrid CPU Power Supply Controller

compatible with both Parallel (PVI) and Serial

(SVI) protocols for AMD Processors.

■ Dual Over-Current protection:

Average and per-Phase

■ Load indicator (CORE section)

■ Voltage positioning

The device embeds two independent control

loops for the CPU core and the integrated NB,

each one with its own set of protections. L6740L

is able to work in Single-Plane mode, addressing

only the CORE Section, according to the parallel

DAC codification. When in Dual-Plane mode, it is

compatible with the AMD SVI specification

addressing the CPU and NB voltages according

to the SVI bus commands.

■ Dual remote sense

■ Adjustable independent reference offset

■ Feedback disconnection protection

■ Programmable OV protection

■ Oscillator internally fixed at 150kHz externally

adjustable

■ LSLess startup to manage Pre-biased output

■ Flexible driver support

The Dual-Edge Asynchronous Architecture is

optimized by LTB technology allowing fast load-

transient response minimizing the output capaci-

tor and reducing the total BOM cost.

■ HTQFP48 package

PSI management allows the device to selectively

turn-off phases when the CPU is in low-power

states increasing the over-all efficiency.

Applications

■ Hybrid High-Current VRM / VRD for Desktop /

Server / Workstation / IPC CPUs supporting

PVI and SVI interface

Fast protection against load over current is pro-

vided for both the Sections. Furthermore, feed-

back disconnection protection prevents from

damaging the load in case of misconnections in

the system board..

■ High-density DC / DC converters
