STMicroelectronics L6751B
The L6751B 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 pinstrapping and PMBus interface. The device features up to 6-phase programmable operation for the multi-phase section and a singlephase with independent control loops. When configured for memory supply, single-phase (VTT) reference is always tracking multi-phases (VDDQ) scaled by a factor of 2.| Part No. | L6751B |
