STMicroelectronics L6751C
The L6751C device is a universal digitally controlled dual PWM DC-DC designed to power Intel’s VR12 and AMD SVI processors and memories: all required parameters are programmable through dedicated pin-strapping and PMBus interface. The device features up to 6-phase programmable operation for multi-phase sections and a single-phase with independent control loops. When configured for memory supply, single-phase (VTT) reference is always tracking multi-phase (VDDQ) scaled by a factor of 2.| Part No. | L6751C |
