L6740L - Hybrid controller

Datasheet Summary

Description

L6740L is a hybrid CPU Power Supply Controller compatible with both Parallel (PVI) and Serial (SVI) protocols for AMD Processors.

The device embeds two independent control loops for the CPU core and the integrated NB, each one with its own set of protections.

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 LTB technologyTM.
PSI management to increase efficiency in Light-Load conditions.
Dual Over-Current protection: Average and per-Phase.
Load indicator (CORE section).
Voltage positioning.
Dual remote sense.
Adjustable independent reference offset.
Feedback disconnection protection.
