1 / 44 page  August 2007 Rev 2 1/44 1 L6740L Hybrid controller (4+1) for AMD SVID and PVID processors 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 ■ Flexible driver support ■ HTQFP48 package Applications ■ Hybrid High-Current VRM / VRD for Desktop / Server / Workstation / IPC CPUs supporting PVI and SVI interface ■ High-density DC / DC converters 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. 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 load- transient response minimizing the output capaci- tor 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 pro- vided for both the Sections. Furthermore, feed- back disconnection protection prevents from damaging the load in case of misconnections in the system board.. HTQFP48 Table 1.
