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.

L6756 2/3/4 phase buck controller for VR10, VR11.1 and AM2 processor applications
The device assures fast protection against load over current and under / over voltage. Feedback disconnection prevents from damaging the load in case of misconnections in the system board. Low-Side-Less start-up allows soft-start over prebiased output avoiding dangerous current return through the main inductors as well as negative spike at the load side. L6756 is available in VFQFPN40 7x7 mm package.

L6711 3 Phase controller with dynamic VID and selectable DACs
The device implements a three phase step-down controller with a 120° phase-shift between each phase with integrated high current drivers in a compact 7x7mm body package with exposed pad. The device embeds selectable DAC: the output voltage ranges from 0.8185V to 1.5810V with 12.5mV steps (VID_SEL = OPEN) or from 0.800V to 1.550V with 25mV steps (VID_SEL = GND; VID5 drives an optional +25mV offset) managing dynamic VID with 0.5% accuracy over line and temp variations. Additional programmable offset can be added to the voltage reference with a single external resistor.

L6714 4 phase controller with embedded drivers for Intel VR10, VR11 and AMD 6Bit CPUs
L6714 implements a four phase step-down controller with 90º phase-shift between each phase with integrated high current drivers in a compact 10mm x 10mm body package with exposed pad. The device embeds selectable DACs: the output voltage ranges up to 1.60000V (both Intel VR10.x and VR11 DAC) or up to 1.5500V (AMD 6Bit DAC) managing D-VID with ±0.5% output voltage accuracy over line and temperature variations. Additional programmable offset can be added to the reference voltage with a single external resistor.
