L6740L Hybrid controller

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

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
■ Programmable OV protection
■ Oscillator internally fixed at 150kHz externally adjustable
■ LSLess startup to manage Pre-biased output
■ Flexib.
