L6740L is a hybrid CPU power supply controller for AMD processors, compatible with both parallel (PVI) and serial (SVI) protocols. 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. The dual-edge asynchronous architecturetm ensures high performance and high efficiency.
