L6740L Datasheet Hybrid Controller

Manufacturer: STMicroelectronics

Overview: L6740L Hybrid controller (4+1) for AMD SVID and PVID processors.

General Description

L6740L is a hybrid CPU Power Supply Controller patible 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.

L6740L is able to work in Single-Plane mode, addressing only the CORE Section, according to the parallel DAC codification.

Key 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.
