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

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 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 Architecture is optimized by LTB technologyTM allowing fast loadtransient response minimizing the output capacitor and reducing the total BOM cost.

PSI management allows the device to selectively turn-off phases when the CPU is in low-power states increasing the over-all efficiency.

Fast protection against load over current is provided for both the Sections. Furthermore, feedback disconnection protection prevents from damaging the load in case of misconnections in the system board
